A plain washer (or ‘flat washer’) is a flat annular or ring, often of metal, used to spread the load of a screwed fastening. Additionally, a plain washer may be used when the hole is a larger diameter than the fixing nut. Plain washers, which spread a load, and prevent damage to the surface being fixed, or provide some sort of insulation such as electrical. Washers are usually metal High quality bolted joints require hardened steel washers to prevent the loss of preload after the torque is applied. A cotter pin, as a split pin or cotter key is a metal fastener with two tines that are bent during installation, similar to a staple or rivet. Typically made of thick wire with a half-circular cross section, split pins come in multiple sizes and types.
There are signs that manufacturers and stockists are increasingly listing both names cotter pin and split pin together to avoid confusion; this led to the term split cotter sometimes being used for a split pin. We manufacture cotter pins in 5/64” to 5/8″ & 2 to 16mm diameter. We also manufacture cotter-pins in BRASS, COPPER, BRONZE, AND STAINLESS STEEL materials as well as per standards DIN 94, ISO 1234 , BS 1574, etc.
