Manufacturing Steel Semi-Tubular Rivets

● Steel Semi-Tubular Rivets is made of the steel material. It can be used in many applications. They are commonly used in brake lining, clutch button, clutch facing, hardware tools, and other industries. Semi Tubular rivets are set by deforming the hole formed in the end of the shank of the rivet. This can be done using a hand held punch or in high volume applications, fully automatically using a purpose built riveting machine. The correct specification of the rivet is the key to a successful application. The load is stronger than that of hollow rivet, which is mainly used for riveting occasions with little load.

● We support customized and can also manufacture non-standard fasteners according to your drawings.

Steel Semi-Tubular Rivets Differ from Other Rivets

Rivets are essential components used in a wide range of applications, from construction and manufacturing to automotive and aerospace industries. One of the most common types of rivets is the steel semi-tubular rivet, which offers several unique advantages over other types of rivets.

Steel semi-tubular rivets are a type of fastener that has a partially-formed hollow shank, which makes them different from solid rivets that have a completely solid shank. The semi-tubular shank allows for the insertion of a mandrel, which is used to expand the rivet and form a permanent connection between two or more materials.

Compared to other types of rivets, such as fully-tubular and solid rivets, steel semi-tubular rivets are easier and faster to install. They require less force to set, making them ideal for applications where a high volume of rivets needs to be installed quickly. Additionally, the partially-hollow shank allows for more flexibility in terms of material thickness, as the mandrel can be adjusted to suit a range of materials.

Fully-tubular rivets, on the other hand, have a completely hollow shank, which makes them more suited to applications where a water-tight seal or an airtight seal is required. They are often used in applications such as air conditioning units, where the rivet must seal against moisture and dust.

Solid rivets, on the other hand, are a type of rivet that has a completely solid shank. Solid rivets offer excellent strength and durability, making them ideal for high-stress applications such as aircraft construction. However, they are more difficult and time-consuming to install than semi-tubular rivets and require specialized equipment.

In terms of applications, steel semi-tubular rivets are commonly used in a wide range of industries, including automotive, electronics, and construction. They are often used to connect thin-gauge materials, such as sheet metal or plastic, as well as thicker materials, such as leather or cloth. They are also often used in applications where a low-profile connection is required, such as in electronic devices.

In the automotive industry, steel semi-tubular rivets are often used to attach brake linings to the brake shoes or to attach the lining to the brake pads. They are also used to attach body panels and trim pieces to the car's frame. In the construction industry, semi-tubular rivets are used to connect steel or aluminum frames, attach cladding, and fasten insulation.

Steel Semi-Tubular are Suitable for Wet Environments?

Steel semi-tubular rivets can be used in wet or humid environments, including marine or coastal installations, but their resistance to corrosion under these conditions depends on several factors.

One of the most critical factors is the type of steel used in the rivets. Stainless steel is often the best choice for use in wet or humid environments because it contains a minimum of 10.5% chromium, which provides excellent resistance to corrosion. Stainless steel semi-tubular rivets are also resistant to pitting and crevice corrosion, which can occur in marine environments.

Another factor that affects the corrosion resistance of steel semi-tubular rivets is the thickness of the plating or coating on the surface of the rivet. Zinc plating is a common coating used on steel rivets to improve their corrosion resistance. Zinc provides a sacrificial layer that corrodes in place of the steel, protecting the underlying metal from corrosion. However, zinc plating is not as effective as stainless steel for use in marine or coastal environments.

In addition to the type of steel and coating, the design of the rivet and the joint it is used in can also affect its resistance to corrosion. Semi-tubular rivets are partially hollow, which allows water and other fluids to penetrate the joint. This can lead to corrosion if the joint is not properly designed and sealed. To prevent corrosion, it is essential to ensure that the joint is adequately sealed and that the rivet is used in a design that allows for adequate drainage of fluids.

When used in marine or coastal environments, steel semi-tubular rivets are often used in applications such as shipbuilding, oil rigs, and coastal infrastructure. These applications require a fastener that can withstand exposure to saltwater, high humidity, and other harsh conditions. Steel semi-tubular rivets are a popular choice in these applications because they are easy to install and can provide a secure, long-lasting joint.

In addition to marine and coastal applications, steel semi-tubular rivets are commonly used in a variety of other applications, including automotive, construction, and electronics. Solid rivets are often used in applications where a permanent joint is required, such as in structural steel construction, while fully-tubular rivets are commonly used in applications where a watertight seal is required, such as in plumbing and electrical conduit.
