Cotter PinsStanho cotter pins feature extended prong square ends made from steel, stainless steel, and brass materials in a wide variety of dimensions. Our American made cotter pins are durable and cost effective.

Used for fastening, cotter pins are half-round wires that are folded over and looped at one end, creating a head. Cotter pins anchor various assemblies by insertion through a drilled hole in a shaft or bolt and then spread the points to lock the assembly into position.
