Metric Cotter Pin / Stainless Steel

Commonly used to secure castle nuts, cotter pins have two tines that are bent during install. The cotter pin passes through the hole of the fastener, the two tines are then opened and bent to secure both parts of the assembly together.

One tine of the cotter pin is longer than the other, which makes separating the tines for installation fast and easy. The length of the split pin is measured by the SHORTER tine.

A2 Stainless Steel cotter pins provide corrosion and chemical resistance and are suitable for general use. Commonly used in damp environments for corrosion resistance, popular across a wide range of industries: automotive, agriculture, food processing, clean energy, etc.

For any application involving marine (salt water), use A4 / 316 Stainless Steel material, available as special order.

Also known as split pin, cotter key, or extended prong.
