Dimensional data for M36 T-Slot Nuts (DIN 508) to DIN 508, with the drive and the installation notes for this type.
Values are taken from the governing standard rather than from a general machine-thread table, because this type is not selected on one.
M36 Dimensional Row (DIN 508)
| Size | T-slot width a (mm) | Nut width b (mm) | Total height h (mm) | Neck height k (mm) | Chamfer f (mm) | Reference standard |
|---|---|---|---|---|---|---|
| M36 | 42 | 65 | 52 | 26 | 6 | DIN 508 |
Spanner & Drive for M36 T-Slot Nuts (DIN 508)
Drive geometry for M36 T-Slot Nuts (DIN 508) is given by the row above; match the tool to the listed values.
Tightening Torque for M36
| Class 8.8 (dry, ~µ 0.125) | ≈ 2523 Nm |
|---|---|
| Class 10.9 (dry, ~µ 0.125) | ≈ 3593 Nm |
| Class 12.9 (dry, ~µ 0.125) | ≈ 4204 Nm |
Indicative dry-joint values. Lubrication can lower the required torque by 15–25%. Always confirm against the joint design, especially when going up a strength class.
Proof Load & Strength for M36
Nuts are graded to ISO 898-2 by the proof load the nut itself will hold (classes 04, 05, 5, 6, 8, 10 and 12), not by the 8.8 / 10.9 / 12.9 scale used for bolts. A class-8 nut is the correct mate for a class-8.8 bolt, and the joint is designed on the bolt, so no bolt-tension figure is quoted here.
Installation Tips for M36 T-Slot Nuts (DIN 508)
- At M36 the stretch in the bolt becomes the controlling factor — for critical joints, use angle-controlled or stretch-controlled tightening instead of pure torque.
Mating Parts for M36
Pair M36 with the matching M36 bolt or screw, plus a M36 flat washer where required to distribute load on softer materials.
