⚡ At a Glance
- • Holding Strength: R-shaped spring split design locks bolts and pins firmly to prevent loosening
- • Best for: Automotive repairs, lawnmowers, small engines and general workshop fastening
- • Not ideal for: Applications that require different diameters or non-standard lengths
304 stainless steel construction resists rust while the 3.5mm wire and 75mm length suit common shaft sizes. R-shaped R-clips offer reusable, high-temperature resistant fastening for demanding applications.
Vibration-resistant locking – thanks to the R-shaped spring split design
R-shaped spring split pins apply even pressure around a bolt or shaft, with the opening oriented outward for a secure lock. Press-fit installation holds pins in place while resisting axial movement under vibration.
Firm retention reduces the chance of nuts or shafts working loose during operation. Ideal for machines and mowers subject to regular vibration.
Long-term corrosion resistance – with 304 stainless steel construction
304 stainless steel offers high chromium content that forms a passive oxide layer, preventing surface rust and resisting chemical exposure and moisture. The material also retains strength at elevated temperatures.
Reliable performance outdoors and in damp environments, reducing the need for frequent replacement. Suitable for workshop and garden equipment exposed to the elements.
Fast, tool-free maintenance – with simple R-clip installation
Align one end of the pin with the hole, then press the R-clip into place until fully inserted with the opening facing outward. R-clips are designed for repeated removal and refitting without tools.
Quicker servicing and less downtime during repairs, useful for regular maintenance on small engines and power tools. Reusability saves time and reduces waste.
