What is a roll pin?

A roll pin, also known as a spring pin or coiled spring pin, is a type of fastener used to secure two or more items together. It is made of a specially shaped metal wire, which is coiled to form a helical spring.

Roll pins are used in a variety of applications, including automotive and industrial machinery, construction equipment, and consumer products. They are often used in places where other types of fasteners, such as screws or nails, would be impractical or ineffective.

Roll pins come in a variety of sizes and materials, including steel, stainless steel, and brass. They are typically installed by first pressing them into a pre-drilled hole, and then tapping them into place with a hammer or other tool.

One of the advantages of roll pins is that they can absorb shock and vibration, making them ideal for use in applications where there is a lot of movement or stress. They are also easy to install and remove, making them a popular choice for many different types of projects.
