Heavy Duty Coiled Spring Pins

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.
Wear-Resistant 400 Series Stainless Steel—Our most wear-resistant stainless steel pins, these are good for pivoting parts that create a lot of friction. They hold up in environments that experience occasional moisture, but they're not as corrosion resistant as 18-8 and 316 stainless steel.
