What is lynch pin?

A lynch pin, also known as a linchpin or a lynchpin, is a fastener typically used to secure a wheel or axle to a trailer or other vehicle. It is a simple and effective way to keep parts securely connected while allowing for easy removal when needed.

Lynch pins consist of a pin with a ring or loop at one end and a series of notches or grooves along the length of the pin. The pin is inserted through a hole in the wheel or axle and then turned so that the ring or loop sits in one of the notches, locking the pin in place.

These pins are commonly used in agriculture, transportation, construction, and other industries where equipment and vehicles need to be quickly and easily connected and disconnected. Lynch pins come in various sizes and materials, including steel, stainless steel, and zinc-plated steel, to accommodate different applications and environments.

Overall, lynch pins are a reliable and versatile fastening solution that provides a quick and secure way to connect and secure wheels, axles, and other components on vehicles and equipment.
