A spring pin (also called tension pin or roll pin) is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the hole diameter, and a chamfer on either one or both ends to facilitate starting the pin into the hole. The spring action of the pin allows it to compress as it assumes the diameter of the hole. The force exerted by the pin against the hole wall retains it in the hole, therefore a spring pin is considered a self-retaining fastener. Spring pins may be used to retain a shaft as a journal in a plain bearing, as a type of key to fasten one shaft to another, or to precisely fasten flat faces of mating parts together through symmetric hole locations.

Slotted spring pins are cylindrical pins rolled from a strip of material with a slot to allow the pin to have some flexibility during insertion. Slotted spring pins are also known as roll pins or “C” pins.

We have the largest selection of custom pins available anywhere. A fastening pin, such as a dowel pin or clevis pin, provides strength when you secure your materials. A metal cotter pin can be bent during installation to act as a staple or spring pin. A hitch pin assembly ensures that your trailer is secure by dropping the pin in place and locking. A steel-grade, industrial safety pin locates, aligns, and safely secures components. Rely on Ever Hardware for industrial pins that secure your materials in place.
