This is the complete dimension chart for DIN 6799 E-clips (radially fitted retaining rings), covering all 17 standard sizes we stock from 0.8 to 24 mm nominal. E-clips are sized by their groove diameter, and each size serves a range of shaft diameters - both are listed below.
Unlike DIN 471 circlips, E-clips slide onto the groove sideways - no pliers, no axial access needed. For the axial-install families, see the DIN 471 and DIN 472 charts.
How to Read the Chart
- Nominal size - equals the groove diameter d₂. This is the size you order.
- Fits shaft Ø - the range of shaft diameters the size is designed to retain.
- Groove Ø - the diameter the shaft groove is machined to (= nominal).
- Clip outer Ø - the outside diameter of the installed clip; check clearance to neighbouring parts.
- Thickness - the axial thickness of the clip; the groove must be slightly wider.

Dimensions per our stocked DIN 6799 range. Neighbouring sizes have overlapping shaft ranges - follow the groove diameter on the drawing where one exists.
Groove & Fitting Notes
- The clip grips the groove with spring tension; a worn or oversize groove lets the clip spin or fly off - replace clips that have been removed and refitted repeatedly.
- Fit radially with flat pliers or an E-clip applicator; remove by levering at the open side, never by prying the closed side.
- E-clips suit moderate axial loads. For higher thrust, step up to a DIN 471 circlip with a machined groove.

View Circlip RangeFrequently Asked Questions
What does the nominal size of a DIN 6799 E-clip refer to?
The nominal size of an E-clip equals the groove diameter it clips onto - not the shaft diameter. A 4 mm E-clip fits a 4 mm groove machined on a shaft of roughly 5 to 7 mm diameter. Always select by groove diameter first, then confirm the shaft falls within the listed range.
What size E-clip do I need for a 6 mm shaft?
A 6 mm shaft falls in the shaft range of the 4 mm nominal E-clip (shaft 5 - 7 mm), which fits a 4 mm groove diameter. Machine the groove to 4 mm and fit a DIN 6799 - 4 clip. Note that neighbouring sizes have overlapping shaft ranges, so follow the groove diameter on your drawing where one exists.
Do E-clips need circlip pliers?
No. E-clips install radially - they push sideways onto the groove with ordinary flat pliers or an applicator tool and snap into place. That makes them faster than DIN 471 circlips in assembly work and usable where there is no axial access to the shaft end.
Are E-clips available in stainless steel?
Yes. We stock DIN 6799 E-clips in carbon spring steel as standard, and SS 304 for corrosive environments - see the SS 304 tab in our pricelist for stainless E-clip rates from 1.5 to 19 mm nominal.
