R-Pin

An R-pin is a reusable fastener with a looped head and two legs that spring apart to hold a part in place. It is often used as a quick release pin for shafts or clevis joints.

An R-pin passes through a hole in a shaft or clevis to hold parts in place. It often works with a washer or a split pin and removes by hand for quick release. A plain hole of matching diameter suits it.

Hot-dipped galvanising gives a thick zinc coating for outdoor or corrosive conditions. Plain finish has no added coating and suits dry indoor use. PTFE coating reduces friction and helps with repeated insertion and removal.

R-pins are often made in steel, stainless steel 304 or 316, or brass. Stainless steel 316 gives better corrosion resistance than 304. Steel grades offer high strength for demanding loads.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and a material test certificate. Check the leg spring, the straightness and the coating on receipt.
