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.

Install these pins into a hole slightly smaller than the pin diameter. They have at least one chamfered end, which means the end is angled to make insertion easier.

The nominal diameter of the pin is the same as the receiving hole diameter. The recommended hole tolerance is ISO H12.

The pins can be easily removed using a mandrel and reused several times.
