    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.
    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.
    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.
