R Clips

About R Clips

R clips, also known as hairpin cotter pins or spring cotter pins, are essential fastening components used to secure clevis pins, shafts, and axles in countless mechanical assemblies. Characterised by their distinctive R-shaped design with a looped head and two parallel legs, these clips provide quick-release fastening solutions that can be easily installed and removed without tools. MyToolShed.co.uk stocks quality R clip assortments from trusted brands like Sealey, ensuring tradespeople and DIY enthusiasts have reliable fasteners readily available for both professional applications and workshop projects.

Unlike split pins that require bending and can be difficult to remove, R clips offer a reusable fastening solution that maintains secure retention whilst allowing for repeated disassembly. Available in various sizes to accommodate different pin and shaft diameters, these galvanised or stainless steel clips resist corrosion and provide long-lasting performance in demanding environments. An assorted kit ensures you'll have the correct size on hand when needed, eliminating costly downtime waiting for specific fasteners.

Applications

R clips are utilised across numerous trades and industries, including:

• Agricultural mechanics – securing pins on tractors, implements, and farm equipment
• Automotive and vehicle repair – retention of throttle linkages, brake components, and suspension parts
• Plant and machinery maintenance – quick-release fastening on construction equipment
• Marine engineering – corrosion-resistant fastening in boat trailers and marine machinery
• Manufacturing and assembly – production line equipment and industrial machinery
• General engineering workshops – versatile fastening solutions for custom fabrications
• DIY and home mechanics – garden machinery, trailers, and general maintenance projects

Choosing The Right R Clips

When selecting R clips from MyToolShed.co.uk, consider these key factors:

• Pin diameter – measure the clevis pin or shaft diameter accurately; the R clip must match precisely for secure retention
• Material and finish – galvanised steel suits most applications, whilst stainless steel offers superior corrosion resistance for marine or outdoor use
• Wire thickness – heavier gauge wire provides stronger retention for high-vibration or critical applications
• Assortment kits – comprehensive sets like the Sealey 150-piece assortment provide multiple sizes in organised storage, ideal for workshops and mobile mechanics
• Quantity requirements – consider how frequently you use R clips and whether bulk quantities or assortments offer better value
• Working environment – harsh conditions require higher-grade materials to prevent premature failure

Frequently Asked Questions

What's the difference between an R clip and a split pin?

R clips feature a spring-like design that can be installed and removed repeatedly without tools, whilst split pins require the legs to be bent for installation and typically cannot be reused. R clips offer quicker assembly and disassembly, making them ideal for applications requiring regular maintenance access.

How do I install an R clip correctly?

Simply compress the two legs of the R clip together and insert through the hole in the clevis pin or shaft. Once through, the spring tension causes the legs to separate, securing the clip in place. The looped head prevents the clip from pulling through whilst providing a grip point for removal.

Are R clips reusable?

Yes, R clips are designed for multiple uses. Provided they haven't been damaged or excessively corroded, they maintain their spring tension and can be removed and reinstalled numerous times, making them a cost-effective fastening solution for regular maintenance applications.
