Hinge Pin

- Mar 21, 2018 -

A hinge pin is a piece of cylindrical metal that holds together the two arms of a hinge in such a manner that the arms can freely pivot around the pin. A basic hinge has three parts: the hinge pin and two arms. For those two arms, one is typically attached to a base or foundation intended not to move, and the other is attached to a door, hatch or other object for which movement is desired. These are typically assembled in such a manner as to allow easy movement of the arms around the pin within a limited range of motion.
