Coiled Spring Pins

The best spring pins for joining parts exposed to vibration and shock. They're often used in power transmission, automation, and other assemblies with constant motion and sudden starts and stops. Because of their spiral shape, they flex to conform to holes that aren’t perfectly round.

Spring Steel—These pins won't deform from stress and vibration. Although they're stronger than stainless steel, they're best for dry environments since moisture will cause them to rust.

Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.

Coiled Spring Pin Assortments

The best spring pins for shock and vibration, these assortments secure a variety of parts. They're often used in power transmission, automation, and other assemblies with constant motion and sudden starts and stops. Pins have a spiral shape that flexes to conform to holes that aren’t perfectly round.
