Cotter Pins
Cotter pins are wire formed fasteners used externally in holed applications; they have been around for centuries. These low-cost and highly versatile fasteners are used virtually everywhere. Cotter pins can be installed quickly and with no special tools. Designed to be self-locking, cotter pins provide secure fastening. Most cotter pins are easily removed and reused, saving time and money. Extended prong makes separation of the prongs easier. Square cut prongs have a cleaner visual appearance.
