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 clear zinc plating gives corrosion resistance with a plain bright finish rather than the yellow chromate used on the rest of the line.

• Material: Spring steel wire for repeatable retention
• Finish: Clear zinc plated for corrosion resistance
• Pack: 100 clips per box
• Manufacturer part: 60842
• Reusable - the spring leg flexes back to its retention shape

Sizing: Double HH publishes this clip as fitting a 7/64" cross-hole on pin shafts of 1/4" to 5/8". Measure the cross-hole rather than the pin body; a clip that rattles in an oversize hole will walk out under vibration, and the looped end has to seat against the pin shank so the spring leg can snap over it and hold. The long leg and 100-piece box suit shops, fleets and farms that go through R-clips as a consumable - trailer ramp hinge pins, drawbar pins and 3-point implement pins.

Range: Double HH builds the clear zinc hitchpin clip in wire diameters from 0.042" up to 0.310", so a heavier or lighter clip is available if this one does not suit your pin.

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.
