A pin, or pin. A part usually made of cylindrical wood, metal, or other material, especially one used to hold several separate objects together or to serve as a support for one object hanging from another. The pin is cylindrical at one end and tapered at the other, similar to the shape of a bullet. It is one of the fasteners commonly used in modern mechanical equipment. The diameter of the cylinder is an important data to distinguish its specifications.

Main uses of pins:

1) make positioning parts of two connected parts;

2) make connection parts to ensure that the connected parts can transfer motion and torque.

3) as a security component (safety pin), that is, when the load is too large, the pin is the first to be destroyed, so the preservation of other important parts. At this point, the pin size must be determined based on the condition that it is cut off when overloaded.

Common pins: cylindrical pin, tapered pin, tapered pin, tapered pin, tapered pin, tapered pin, tapered pin, tapered pin, tapered pin, tapered pin, sectional pin, cylindrical slot pin.
