Clamping Lever Dimensions (DIN 99, 50 to 200 mm)
Guide · Updated October 28, 2026
DIN 99 covers one-piece steel clamping levers, straight or angled, 50 to 200 mm long. Values agree across Ganter, Elesa+Ganter, Elesa, Hanser and Schiltz tables except the dashed b and h cells. d4, h and l2 are approximate.

Step by step
- Pick the length: Choose l1 by the torque you need, e.g. 80 mm for an M10 clamp.
- Pick the type: K straight plain bore, M straight threaded, L angled plain bore, N angled threaded.
- Check the bore: Threaded types take d1; plain types have an H7 bore d2 to pin onto a shaft.
- Check the clearance: For angled types allow h and lever length l2 to swing clear.
DIN 99 clamping lever dimensions (mm)
Columns: lever length l1, thread d1 (types M and N), H7 bore d2 (types K and L), hub b, d3, d4 approx, d5, height h approx and lever length l2 approx (angled types).
- l1 | d1 | d2 | b | d3 | d4 | d5 | h | l2
- 50 | M6 | B6 | 9.5 | 8 | 7.5 | 12 | 24 | 48
- 63 | M8 | B8 | — | 10 | 11 | 16 | — | 60
- 80 | M10 | B10 | — | 13 | 15 | 20 | 38 | 76
- 100 | M12 | B12 | — | 16 | 19 | 25 | 47 | 95
- 125 | M16 | B16 | — | 20 | 23.5 | 32 | 59.5 | 119
- 160 | M20 | B20 | — | 25 | 29.5 | 40 | — | 152
- 200 | M24 (N only) | B24 (L only) | — | 32 | 33 | 50 | 97 | 190
Worked example: 80 mm lever
A DIN 99 80 M10 N lever is threaded M10, has a 20 mm hub end d5 and in angled form stands about 38 mm high with a 76 mm lever length.
Common problems
- Lever ends in the wrong spot: use an indexing or adjustable clamping lever instead.
- Lever hits the part: switch between straight and angled forms.
- Lever loosens on a plain shaft: pin through the hub.
FAQ
What is DIN 99 used for?
One-piece steel levers for clamping fixtures, machine slides and adjusting spindles.
Why are some b and h cells dashes?
Hub b differs from 63 mm up (Ganter, Elesa and Hanser give 12, 14.5, 18.5, 24, 30, 40; Schiltz gives 12.5, 15, 19, 25, 31, 41). h differs at 63 mm (30 vs 30.5) and 160 mm (75.7 vs 76). Those cells are left blank.
Which sizes come straight?
Straight types K and M are sold from 50 to 160 mm; 200 mm is angled only (L and N).
Is there a 40 mm size?
Ganter notes the DIN sheet also lists 40 mm with M5 or B5, but few suppliers stock it.
