FAQs

What is a semi-tubular rivet

A semi-tubular rivet is a type of rivet with a partially hollow end, which makes it easier to install compared to solid rivets. The hollow end deforms during the riveting process, securing the rivet in place without requiring high shear strength. Semi-tubular rivets are commonly used in industries like manufacturing, automotive, and electronics for joining thin materials, offering advantages like simplicity, cost-effectiveness, and ease of installation.

What is the difference between solid and tubular rivets

Solid rivets are made from a single piece of metal, providing high strength and durability, while tubular rivets have a hollow design, making them lighter and easier to install but with slightly lower load capacity. Solid rivets require heating and hammering or pressing for installation, making them ideal for high-stress applications like aerospace and construction. In contrast, tubular rivets are compressed using a setting tool, making them suitable for lighter applications such as automotive panels and electronics. The choice between them depends on strength requirements, weight considerations, and installation ease. View More

Difference between tubular and semi tubular rivets

The main difference between tubular and semi-tubular rivets lies in the depth of their hollow portion. Tubular rivets have a shank hole depth that is at least 112% of the shank diameter, while semi-tubular rivets have a shank hole depth of less than 112% of the shank diameter. Both types are used to join materials together, but the deeper hollow in tubular rivets may offer advantages in specific applications. View More

What does grip range on semi tubular rivet mean

On semi-tubular rivets, the grip range refers to the thickness of the material or the depth that the rivet can effectively hold together. It's the range of material thickness the rivet is designed to join, and it's crucial for proper installation and the strength of the joint. The grip range is not the same as the rivet's length.

What is the difference between a hollow rivet and an eyelet

The key difference between a hollow rivet (also known as a tubular rivet) and an eyelet lies in their purpose and how they're used. A hollow rivet is primarily designed for joining materials, often with a hollow shaft that expands to grip the materials being joined. An eyelet, on the other hand, is a reinforcing piece that creates a stronger, reinforced hole, often for passing items like strings or loops through. View More

How to install semi tubular rivets

Semi-tubular rivets are easy-to-install, permanent fasteners used in various applications. They have a partial hole at one end that allows them to be flared or rolled outward, forming a secure joint with less force than solid rivets. Installation methods range from manual tools like a rivet setter and hammer or a manual squeezer for small projects, to specialized riveting machines for high-volume production. Key to successful installation are selecting the correct rivet size (diameter and length), ensuring proper hole size, and adequately supporting the rivet head during the clinching process. View More
