The M10 size of Pan Head Screws is dimensioned by ISO 1207 / ISO 7045 / DIN 7985. The tables below give the dimensional row from the standard, the drill and spanner sizes that go with it, and the assembly torque per property class. The technical drawing on this page redraws to the exact values selected.
M10 Dimensional Row (ISO 1207 / ISO 7045 / DIN 7985)
| Size | Pitch (mm) | Head diameter dk (mm) | Head height k (mm) | Cross recess | Reference standard |
|---|---|---|---|---|---|
| M10 | 1.5 | 20.0 | 6.0 | PH4 | ISO 1207 / ISO 7045 / DIN 7985 |
Spanner & Drive for M10 Pan Head Screws
M10 Pan Head Screws use a PH4 cross recess. Match the driver bit to the recess (Phillips PH / Pozi PZ are NOT interchangeable).
Hole Sizes for M10
| Coarse-thread pitch (ISO 724) | 1.5 mm |
|---|---|
| Through-hole / clearance (ISO 273 medium) | 11 mm |
| Tapping drill, coarse thread | 8.5 mm |
Tightening Torque for M10
| Class 8.8 (dry, ~µ 0.125) | ≈ 49 Nm |
|---|---|
| Class 10.9 (dry, ~µ 0.125) | ≈ 69 Nm |
| Class 12.9 (dry, ~µ 0.125) | ≈ 83 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 M10
| Tensile stress area As (ISO 898-1) | 58 mm² |
|---|---|
| Proof load, class 8.8 | 34 kN |
| Proof load, class 10.9 | 48 kN |
| Proof load, class 12.9 | 56 kN |
| Min. ultimate tensile, class 8.8 | 46 kN |
Proof load = stress area × proof stress per ISO 898-1. Design joints so the working preload stays below the proof load of the selected class.
Common Applications for M10 Pan Head Screws
M10 Pan Head Screws are commonly specified for machine assembly, general engineering, plant maintenance and OEM equipment.
Installation Tips for M10 Pan Head Screws
- Pozidriv (PZ) drivers ride out of Phillips (PH) recesses and vice versa — confirm the recess marking on the head before assembly.
- For automated assembly, an ACR (Anti-Cam-Out Ribs) or torx-equivalent driver gives noticeably longer bit life than plain PH.
When to Step Up or Down from M10
When the joint preload approaches the proof load of M10 class 8.8, step up to M12 class 8.8 (or move to M10 class 10.9). When the joint is over-specified, M8 often saves weight and cost without losing the safety margin.
