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.

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.

Single / Double Coil R-Clips

Retaining pins or R-clips are stocked in two designs – the single coil for most applications and the double coil for more demanding use.

They are manufactured in either zinc plated or spring steel and the size range is from 1.2mm to 8mm wire diameters.


  • Zinc plated spring steel
  • Stainless steel
