About this retaining ring

This is a retaining ring in 304 Stainless Steel, at strength class A2-70, supplied plain, with an M4 thread and a 50 mm length. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.

A retaining ring locates a component axially on a shaft or inside a bore, seating in a machined groove so the part cannot walk out of position. Used on shafts, bearings, pins and gear assemblies where an axial stop is needed but a shoulder or collar is not possible.

Plain (self-colour) means no coating. On 304 and 316 stainless that is fine — the alloy passivates on its own. On carbon steel it will rust, so choose a coated option instead.

M4 is a metric thread with an 4 mm nominal diameter and a coarse pitch of 0.7 mm (ISO 261). A standard hex head takes a 7 mm spanner across the flats.

Sold by the piece, so one is a valid order. Stock lines leave our warehouse within 24–48 hours of cleared payment, and freight is calculated at checkout from the packed weight and the destination.
