Spring-steel R-clip (also called a hitchpin clip or hairpin cotter) used to secure a hitch pin, clevis pin, or other smooth pin in farm equipment, trailers, lawn-and-garden machinery, and industrial assemblies. The yellow zinc plating gives both corrosion resistance and high field visibility so a dropped clip is easy to spot in grass or shop dirt.

• Wire diameter: 0.093"
• Overall length (long leg): 2-9/16"
• Material: Spring steel wire for repeatable retention
• Finish: Yellow zinc plated for corrosion resistance and visibility
• Pack: 100 clips per polybag
• Reusable - the spring leg flexes back to its retention shape

Pin fit: Standard fit for hitch pins and clevis pins with 1/4" to 5/16" shank diameters (a 1/8" cross-hole in the pin shank is the typical drilling).

Length context: Mid-length leg suits typical farm and utility trailer applications - sub-compact tractor 3-point implements, drawbar pins, and trailer ramp hinge pins.

Installation tip: Slip the straight leg through the cross-hole until the looped end seats against the pin, then squeeze the spring leg to its parallel position so it grips the pin shank. To remove, pull straight back on the looped end - do not pry sideways with a screwdriver, which work-hardens the wire and shortens clip life. Keep a spare bag on the equipment - hitchpin clips are easy to lose during field service.
