What are non-ferrous fasteners?

Non-ferrous fasteners are fasteners that are made from materials that do not contain iron or have very low iron content. These materials are typically more resistant to corrosion and rust than ferrous materials, making them ideal for use in applications where high corrosion resistance is required.

Common non-ferrous materials used in fasteners include brass, bronze, copper, aluminum, titanium, and stainless steel. Non-ferrous fasteners are commonly used in marine, chemical, and other corrosive environments where ferrous materials would be prone to rust and deterioration.

Some examples of non-ferrous fasteners include bolts, nuts, screws, washers, and rivets made from non-ferrous materials. These fasteners may be used in applications such as boat building, plumbing, and electronics, among others.

What are the different types of non-ferrous fasteners?

There are several different types of non-ferrous fasteners, each with their own unique properties and applications. Here are some of the most common types:

1. Brass fasteners: Brass is a copper alloy that is highly resistant to corrosion and has good strength and ductility. Brass fasteners are commonly used in electrical, plumbing, and marine applications.

2. Bronze fasteners: Bronze is another copper alloy that is known for its high strength, durability, and corrosion resistance. Bronze fasteners are often used in marine and oil and gas applications.

3. Copper fasteners: Copper is a highly conductive and malleable metal that is often used in electrical applications. Copper fasteners are also used in plumbing, roofing, and other applications where corrosion resistance is important.

4. Aluminum fasteners: Aluminum is a lightweight metal that has good strength and excellent corrosion resistance. Aluminum fasteners are often used in aerospace, automotive, and construction applications.

5. Titanium fasteners: Titanium is a strong, lightweight metal that is highly resistant to corrosion. Titanium fasteners are commonly used in aerospace, medical, and military applications.

6. Stainless steel fasteners: Stainless steel fasteners are an excellent choice for outdoor applications for several reasons, including corrosion resistance, strength, longevity and aesthetics.

These are just a few examples of the different types of non-ferrous fasteners available. The choice of fastener material will depend on the specific application and the desired properties of the fastener, such as strength, corrosion resistance, conductivity, and weight.

In what applications would someone want to use non-ferrous fasteners?

Non-ferrous fasteners are often used in applications where resistance to corrosion or rust is important. This is because ferrous materials, such as steel, are prone to rust and deterioration when exposed to moisture, chemicals, and other corrosive environments.

Here are some specific applications where non-ferrous fasteners are commonly used:

1. Marine applications: Non-ferrous fasteners are often used in boats and other marine equipment due to their resistance to corrosion in saltwater environments.

Stainless steel fasteners are highly durable and can withstand extreme temperatures, making them suitable for use in a wide range of industries and applications. Some of the most common reasons for using stainless steel fasteners are their corrosion resistance, durability, aesthetics and strength. While most users of stainless steel fasteners are familiar with these benefits as a whole, far fewer people are know what the different types of stainless steel are and how their properties may affect any given application.

The two most common types of stainless steel used in fastener production are Austenitic Stainless Steel and Martensitic Stainless Steel. The main difference between Austenitic Stainless Steel and Martensitic Stainless Steel is their composition and microstructure, which gives them different mechanical and physical properties.

Austenitic Stainless Steel contains high levels of chromium and nickel, and sometimes molybdenum, which makes it highly resistant to corrosion and oxidation. This type of stainless steel has a face-centered cubic (FCC) crystal structure, which gives it good ductility, toughness, and excellent formability. Austenitic stainless steel is often used in applications that require good corrosion resistance, such as in food processing, chemical, and pharmaceutical industries. There are several types of Austenitic Stainless Steel, including:

1. AISI 304: This is the most common type of Austenitic Stainless Steel, containing 18% chromium and 8% nickel, which gives it another name people use, 18-8 Stainless Steel. It has good corrosion resistance, formability, and weldability, and is often used in applications that require general corrosion resistance, such as in food processing, chemical, and architectural industries.

2. AISI 316: This type of Austenitic Stainless Steel contains 16% to 18% chromium, 10% to 14% nickel, and 2% to 3% molybdenum. It has better corrosion resistance than AISI 304, especially in chloride environments, and is often used in applications that require high corrosion resistance, such as in marine, medical, and chemical industries.

3. AISI 321: This type of Austenitic Stainless Steel contains 17% to 19% chromium, 9% to 12% nickel, and 0.3% to 0.7% titanium. It has good corrosion resistance and high-temperature strength, making it suitable for use in applications that require resistance to high temperatures, such as in exhaust systems and jet engines.

4. AISI 347: This type of Austenitic Stainless Steel contains 17% to 19% chromium, 9% to 13% nickel, and 0.3% to 0.7% columbium. It has similar properties to AISI 321 but has better corrosion resistance in high-temperature applications.

5. AISI 201: This type of Austenitic Stainless Steel contains 16% to 18% chromium and 3.5% to 5.5% nickel. It has lower corrosion resistance than AISI 304 but is more affordable and has good formability and weldability. It is often used in applications that require low to moderate corrosion resistance, such as in automotive trim and kitchenware.

On the other hand, Martensitic Stainless Steel contains high levels of carbon and low levels of nickel, which gives it high strength, hardness, and wear resistance. This type of stainless steel has a body-centered cubic (BCC) crystal structure, which makes it less ductile than Austenitic Stainless Steel. Martensitic stainless steel is often used in applications that require high strength and wear resistance, such as in knives, tools, and turbine blades. The types of Martensitic Stainless Steel include:

1. AISI 410: This type of Martensitic Stainless Steel contains 11.5% to 13.5% chromium and has a moderate level of corrosion resistance. It is often used in applications that require high strength, hardness, and wear resistance, such as in cutlery, pumps, and valves.

2. AISI 420: This type of Martensitic Stainless Steel contains 12% to 14% chromium and 0.15% to 0.40% carbon. It has higher corrosion resistance than AISI 410 and is often used in applications that require high strength, hardness, and wear resistance, such as in surgical instruments, dental equipment, and turbine blades.

3. AISI 440: This type of Martensitic Stainless Steel contains 16% to 18% chromium and 0.75% to 1.20% carbon. It has the highest level of hardness and wear resistance among Martensitic Stainless Steel, making it suitable for use in high-performance cutting tools, bearings, and valves.

4. AISI 431: This type of Martensitic Stainless Steel contains 15% to 17% chromium, 1.25% to 2.50% nickel, and 0.12% to 0.22% carbon. It has good corrosion resistance and high strength, making it suitable for use in pumps, valves, and marine applications.

In summary, Austenitic Stainless Steel and Martensitic Stainless Steel have different compositions and microstructures, which give them different properties. Austenitic Stainless Steel is highly corrosion-resistant, ductile, and formable, while Martensitic Stainless Steel is highly wear-resistant, hard, and strong. The choice between the two types of stainless steel depends on the specific application requirements and conditions.

What is a structural bolt?

A structural bolt is a type of fastener specifically designed for use in the construction industry. Structural bolts are designed to be used in tension, meaning that they are tightened in such a way that they create a clamping force that holds two or more components together. Structural bolts are typically made from a high-strength material, such as alloy steel, and are used to connect heavy load-bearing members in structures such as bridges, buildings, and other types of infrastructure. They are usually installed using a torque wrench, which allows for precise control of the clamping force applied to the bolt.

What does A325 mean in fasteners?

A325 is a type of fastener specification for structural bolts. It is a specification established by the American Society for Testing and Materials (ASTM) for medium-strength steel bolts, studs, and other fasteners. The specification covers high-strength bolts that are intended for use in structural connections. Structural bolts made to the A325 specification are made from a medium-carbon steel that has been quenched and tempered, which gives them a high level of tensile strength and resistance to fatigue. They are also designed with a specific head shape and thread configuration, which allows them to be used with a corresponding nut and washer to create a structural connection. The A325 specification is typically used in the construction industry, particularly in the United States, to specify the material and performance requirements for structural bolts.

When do A325 bolts need to be used?

A325 bolts are typically used in structural connections where high tensile strength and resistance to fatigue are required. They are often used to connect heavy load-bearing members in structures such as bridges, buildings, and other types of infrastructure. The A325 specification is generally used in the United States, and it is often specified by building codes and engineering standards for use in structural connections.

In general, A325 bolts should be used whenever high-strength structural bolts are required in a connection. They are particularly well-suited for use in applications where the bolts will be subjected to high levels of stress, such as in load-bearing connections or in connections that will be subjected to dynamic loads. They are also often used in connections where the bolts will be exposed to harsh environmental conditions, such as in outdoor structures or in marine applications.

Are there any downsides to using A325 bolts?

One potential downside of using A325 bolts is that they are more expensive than some other types of bolts. Because they are made from high-strength steel and are designed for use in structural connections, they tend to be more expensive than bolts made from lower-strength materials.

Another potential downside of A325 bolts is that they require a specific installation process. The bolts must be tightened to a specific torque value in order to achieve the required clamping force in the connection. This requires the use of a torque wrench, which can add to the cost and complexity of the installation process.

Finally, A325 bolts are not suitable for use in all applications. They are designed specifically for use in structural connections, and they may not be appropriate for use in other types of applications where different types of bolts may be more suitable.

What type of anchors work best in concrete?

There are several types of anchors that can be used in concrete, each with its own advantages and disadvantages. Some of the most common types of anchors include:

1. Wedge anchors: These are simple and inexpensive, and they work well in solid concrete. They consist of a threaded rod with a sloping wedge on one end and a nut on the other end. When the nut is tightened, the wedge expands, creating a secure hold in the concrete.

2. Drop-in anchors: These are similar to wedge anchors, but they have a pre-expanded sleeve that is inserted into a pre-drilled hole in the concrete. When the anchor is tightened, the sleeve collapses around the rod, creating a secure hold.

3. Epoxy anchors: These are the strongest type of concrete anchor, but they require more time and effort to install. They consist of a threaded rod with a two-part epoxy resin that is mixed and applied to the rod before it is inserted into the hole. The epoxy hardens and creates a secure hold in the concrete.

4. Screw anchors: These are similar to wedge anchors, but they have a screw thread on the end rather than a sloping wedge. They are easy to install and work well in both solid and hollow concrete.

In general, wedge anchors and drop-in anchors are the most popular choices for concrete anchor applications, due to their simplicity and effectiveness. Epoxy anchors are the strongest, but they are more expensive and time-consuming to install. Screw anchors are a good choice for lighter loads and where a removable anchor is needed.

What is a concrete screw and how is it used?

A concrete screw is a type of anchor that is used to secure objects to concrete. It consists of a hardened screw with a special thread design that allows it to be easily installed into concrete without the need for pre-drilling.

Concrete screws are particularly useful in situations where it is not practical to use other types of anchors, such as when the concrete is too hard or when the object being attached needs to be easily removed or relocated. They are also a good choice when the load being supported is relatively light, as they are not as strong as some other types of anchors.

To install a concrete screw, you will need a hammer drill and a screwdriver or drill with a screwdriver bit. First, mark the location where you want to install the screw and drill a hole using the hammer drill and a masonry bit. Next, insert the concrete screw into the hole and tighten it using the screwdriver or drill. The screw should be tightened until it is seated firmly in the concrete, but be careful not to overtighten it as this can strip the thread or cause the screw to break.

Concrete screws are a convenient and effective way to secure objects to concrete and are widely used in a variety of applications, including attaching shelves, hanging cabinets, and mounting brackets.

What is an aerated concrete screw?

Aerated concrete screws, also known as light concrete screws, are a type of anchor that is specifically designed for use in aerated or lightweight concrete. Aerated concrete is a type of concrete that is made with tiny air bubbles or pores, which makes it lighter and easier to work with than standard concrete. However, it is also weaker and more prone to crushing and cracking, which can make it more difficult to anchor objects to it.

Aerated concrete screws are designed to be used in aerated concrete without crushing or cracking it. They have a special thread design that allows them to be easily screwed into the aerated concrete, while also providing a strong and secure hold.

To install an aerated concrete screw, you will need a hammer drill and a screwdriver or drill with a screwdriver bit. First, mark the location where you want to install the screw and drill a hole using the hammer drill and a masonry bit. Next, insert the aerated concrete screw into the hole and tighten it using the screwdriver or drill. The screw should be tightened until it is seated firmly in the aerated concrete, but be careful not to overtighten it as this can strip the thread or cause the screw to break.

Aerated concrete screws are a convenient and effective way to anchor objects to aerated concrete, and they are widely used in a variety of applications, including attaching shelves, hanging cabinets, and mounting brackets.

Are there any downsides to using Grade 8 fasteners?

Some potential downsides to using Grade 8 fasteners include:

1. Cost: Grade 8 fasteners are typically more expensive than other grades of fasteners, such as Grade 2 or Grade 5. This can make them a less cost-effective option in some applications.

2. Brittleness: Grade 8 fasteners are made of high-strength alloy steel and are heat-treated to increase their strength. However, this heat-treatment process can also make them more brittle, which can increase the risk of fastener failure if they are subjected to too much stress or strain.

3. Over-tightening: It is important to tighten Grade 8 fasteners to the proper torque specification to ensure that they are secured properly. If they are overtightened, the fasteners can be damaged or even break, which can lead to fastener failure.

4. Compatibility: Grade 8 fasteners may not be compatible with all materials. For example, if they are used to fasten soft materials such as aluminum or brass, the threads may strip or the fasteners may fail due to the lack of sufficient gripping power. It is important to ensure that Grade 8 fasteners are used with materials that they are compatible with to avoid problems.

What does Grade 5 mean in fasteners?

In the context of fasteners, such as screws, bolts, and nuts, "grade 5" refers to the strength of the material used to make the fastener. Grade 5 fasteners are made from medium carbon steel and are heat treated to increase their strength. They are stronger than grade 2 fasteners, but not as strong as grade 8 fasteners. Grade 5 fasteners are commonly used in automotive and construction applications where a higher level of strength is required. They are also sometimes referred to as "heat-treated medium carbon steel" or "medium strength" fasteners.

What are the benefits of using Grade 5 fasteners?

Some benefits of using grade 5 fasteners include:

1. Increased strength: Grade 5 fasteners are made from medium carbon steel and are heat treated to increase their strength, making them suitable for use in applications where a higher level of strength is required.

2. Durability: Grade 5 fasteners are resistant to wear and tear, making them suitable for use in applications where the fasteners will be subjected to repeated loading and unloading.

3. Corrosion resistance: Grade 5 fasteners are coated with a protective finish to help prevent corrosion, making them suitable for use in outdoor or high-moisture environments.

4. Good price-to-strength ratio: Grade 5 fasteners offer a good balance between strength and cost, making them a popular choice in a wide range of applications.

5. Wide availability: Grade 5 fasteners are widely available and can be found at most hardware stores or online retailers.

Are there any possible downsides to using Grade 5 fasteners?

There are a few potential downsides to using grade 5 fasteners:

1. They may not be strong enough for some applications: While grade 5 fasteners are strong, they may not be suitable for use in applications where extremely high levels of strength are required. In these cases, a higher grade fastener, such as a grade 8 fastener, may be necessary.

2. They may be more prone to corrosion: While grade 5 fasteners are coated with a protective finish to help prevent corrosion, they may still be more prone to corrosion than some other grades of fasteners. This can be an issue in applications where corrosion resistance is critical.

3. They may be more expensive than lower grade fasteners: Grade 5 fasteners may be more expensive than lower grade fasteners, such as grade 2 fasteners. This can be an issue in applications where cost is a major consideration.

4. They may be harder to work with: Grade 5 fasteners may be harder to work with than lower grade fasteners due to their increased strength and hardness. This can make them more difficult to cut, drill, or tap, for example.

Overall, the suitability of grade 5 fasteners will depend on the specific requirements of the application. It is important to carefully consider the strength, corrosion resistance, cost, and workability of the fasteners to ensure that they are suitable for the intended use.

Lindapter’s technical support team worked with the client in order to design a suitable connection using Hollo-Bolt, the original expansion bolt for structural steel that requires access to only one side of the HSS. The design incorporated splice connections with pre-drilled holes in the HSS which the Hollo-Bolt could be inserted through to join the roof framework together. Hollo-Bolt Countersunk and Flush Fit head types were specified in critical locations to prevent the heads obstructing the solar panels whilst Hexagonal head Hollo-Bolts were used in less critical locations in the roof framework. A Sheraplex coating was also specified for the Hollo-Bolts to provide a high level of corrosion protection.

The hollow structural sections were manufactured in a fabrication shop where they were cut to length, and holes drilled to suit the requirements of the Hollo-Bolts. The HSS was also galvanized prior to delivery to reduce labor costs and time in the field whilst also ensuring long lasting corrosion protection. Once in the field each finished and coated part was assembled by simply inserting the Hollo-Bolts into the predrilled holes and tightening them with a wrench to the recommended tightening torque. To complete the installation, solar panels were connected to the framework and then the whole roof hoisted into position on steel support columns.
