What this part is
MIDWEST FASTENER 50275 Cotter Pin is a new steel fastener with a zinc-plated finish. It is sized at 3/16 in pin diameter and formed in the classic R-shaped wire clip style. The component is designed to lock round shafts such as axles and clevis pins in automotive and general hardware assemblies.
How it fits into a build
The clip slides through a drilled hole in the shaft and the spring tension holds it in place without tools. Zinc plating adds corrosion resistance for outdoor or under-vehicle exposure. No additional hardware is required beyond the mating pin or axle, freeing up inventory space for other fastener types.
Behaviour under sustained load
Hardened spring wire maintains its grip through repeated vibration and thermal cycles. The zinc coating continues to protect the base steel when the assembly sees moisture, road salt or temperature swings. Buyers who need a reusable quick-release pin or a larger diameter clip should select a different fastener style.
