What is sheer pin?

A shear pin is a device used to protect machinery from damage caused by excessive force or torque. Typically made of metal, the shear pin is designed to break when the machine is subjected to forces beyond its capacity. When this happens, it prevents the machinery from being further damaged and allows for easy repairs. Shear pins are commonly used in large machinery such as tractors, snowblowers, and boats. They work by breaking apart under pressure, which in turn releases the tension and stops the machinery from moving. It is important to replace broken shear pins with new ones that are designed for the specific machine to ensure continued protection.
