Pins
Hairpin cotters, or R-clips, are spring-tempered wire fasteners featuring a straight leg for insertion and a curved belly that snaps over the shaft to provide secure tension. Designed for tool-less installation and repetitive reusability, they serve as axial retainers for clevis pins and unthreaded axles. Their quick-release capability makes them highly suitable for tractor attachments, trailer wheel axles, and industrial linkage maintenance.
Our hairpin cotters are available in a range of sizes, materials, and standards. Contact us for a detailed specifications sheet and competitive bulk pricing.
