Industrial fastening pins or mechanical pins are threadless fasteners used for positioning, connecting, and withstanding shear forces between mechanical parts. There are many types of fastening pins, including clevis pins, cotter pins, cylindrical dowel pins, roll pins, spring pins, ball pins, lynch pins, and safety pins.
The fastening pin has a simple structure, efficient assembly, and stable reliability. It is fixed by friction or tension and is a key component in industrial connection solutions.
