R-Clips (R-Pins) – 304 (A2) Stainless Steel
These 304 (A2) stainless steel R-clips (also called R-pins or hairpin clips) are formed from spring-tempered wire and provide a fast, tool-free way to retain pins and shafts. The single loop and long leg allow quick insertion and removal by hand, while the spring action keeps the clip securely in place.

Frequently Asked Questions
What is an R-clip used for?
An R-clip (R-pin or hairpin clip) is a spring wire clip that retains a clevis pin, hitch pin or shaft. The straight leg goes through the pin hole and the loop snaps over the pin body, holding it axially while allowing removal in seconds without tools.
How do I choose the right R-clip size?
Match the clip to the pin hole diameter — the straight leg must pass through the hole freely, while the loop grips the pin shaft. We stock clips for shaft/pin diameters from 2 to 10 mm.
Why spring-tempered stainless wire?
The spring temper gives the wire its snap: the loop holds itself in place against vibration yet can still be flexed repeatedly for removal. 304 stainless steel adds corrosion resistance for outdoor and agricultural use.
Do you provide material certificates?
Yes. Material test certificates per EN 10204 3.1 are available on request, and our manufacturing is ISO 9001:2015 certified. RoHS and REACH compliance documentation can also be provided.
