Notes for buyers
- Circlips are sized by the shaft or bore they fit, not by any dimension of the ring. A 20 mm DIN 471 ring fits a 20 mm shaft.
- Groove dimensions are what make a ring fit. The dimension tables on our reference pages name the source of every figure.

What is the UNSPSC code for circlips?
31163202, Retaining rings. It covers external circlips (DIN 471), internal circlips (DIN 472) and E-clips (DIN 6799). The class above, 31163200 Retaining hardware, is also valid if your system only accepts class codes.
Is an E-clip classed as a washer?
No. DIN 6799 calls it a retaining washer, but it does the job of a retaining ring and belongs under 31163202. Filing it under 31161800 Washers puts retaining-ring spend in the wrong line of your reports.
