Dimensional data for M6X0.75 Panel Nuts (Thin, Fine Pitch) to DIN 439, 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.
M6X0.75 Dimensional Row (DIN 439)
| Thread size | Pitch (mm) | Across flats s (mm) | Across corners e (mm) | Nut height m (mm) | Typical application | Reference standard |
|---|---|---|---|---|---|---|
| M6x0.75 | 0.75 | 10 | 11.05 | 3.2 | Potentiometer bushing | DIN 439 B |
Spanner & Drive for M6X0.75 Panel Nuts (Thin, Fine Pitch)
Drive geometry for M6X0.75 Panel Nuts (Thin, Fine Pitch) is given by the row above; match the tool to the listed values.
Tightening Torque for M6X0.75
| Class 8.8 (dry, ~µ 0.125) | ≈ 11 Nm |
|---|---|
| Class 10.9 (dry, ~µ 0.125) | ≈ 16 Nm |
| Class 12.9 (dry, ~µ 0.125) | ≈ 19 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 M6X0.75
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 M6X0.75 Panel Nuts (Thin, Fine Pitch)
- At M6X0.75 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 M6X0.75
Pair M6X0.75 with the matching M6X0.75 bolt or screw, plus a M6X0.75 flat washer where required to distribute load on softer materials.
