McMaster 98401A449 Pin, cotter 18-8 SS 3/32 in Dia 2-1/2 Length 100 Per Box

Lock the ends of clevis pins and shafts to keep components in place. Slide these cotter pins into a hole and then bend the prongs outward with pliers to secure. Also known as split pins, one prong is slightly longer than the other for easy opening once inserted. Repeated bending will weaken the pin, so they should not be reused.

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.
