Technifast 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 will spread the stresses out more evenly for a longer life cycle. Retaining clips are also known as spring cotters 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.
