Roll pins are hollow fasteners with a slot running the entire length, allowing it to be squeezed when inserted. They have a beveled chamfer so that the pin can be inserted into slightly smaller hole, compressing as it is driven into place. The outward radial force caused by the compression holds the spring tension pin in place. Essentra offers slotted spring pins in your choice of stainless steel or high carbon steel with either imperial or metric sizes available. Spring dowel pins can be used to replace rivets, taper pins, split pins or bolts. Because of their resistance to shock and vibration roll pins are used as an actuator roll pins, connecting draw rods to actuators. They are commonly used in automotive door locks and latches, steering boxes, pumps and electric motors. They can be used as either alignment pins or fasteners holding two or more objects together.
