Coiled Spring Pins


	End View

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.

Heavy Duty Coiled Spring Pins


	End View

Made of thicker material than our other coiled spring pins, these are about 30% stronger with the same resilience to vibration and shock. They are often used in power transmission, automation, and other assemblies with constant motion and sudden starts and stops. Because of their spiral shape, pins flex to conform to holes that aren’t perfectly round.

Carbon 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.

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.

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.
