Retaining Pin

Torqbolt stock a large range of Retaining Pins (R-Clips) in wire diameters from 1.2mm through to 8mm to meet the requirements of a large range of applications.
Choose from a single coil - or for more durability a double coil R-Clip to spread the stresses out more evenly for a longer life cycle.
Retaining clips are also known as spring cotters and are often used in conjunction with clevis pins when inserted through the shaft, to keep the pin in place.
R-Clips are particularly useful when components are to be quickly assembled or disassembled and are used in a variety of industries including automotive and agriculture.
