Selecting Socket Set Screws, M10, in ISO 4026 / ISO 4029 / DIN 913-916: the dimensional row from the standard plus the tools and hole sizes follow. Use them with the technical drawing below — the drawing redraws to the exact size you pick.
M10 Dimensional Row (ISO 4026 / ISO 4029 / DIN 913-916)
| Size | Pitch (mm) | Hex socket s (mm) | Engagement depth t min (mm) | Point diameter dp (mm) | End type | Reference standard |
|---|---|---|---|---|---|---|
| M10 | 1.5 | 5.0 | 5.0 | 7.0 | Flat point | ISO 4026 / DIN 913-916 |
Spanner & Drive for M10 Socket Set Screws
The hex socket for M10 Socket Set Screws is shown in the spec table — use the matching Allen / hex key (an ISO 2936 hex key set covers the full range). A T-handle Allen key gives the best feel for setting preload by feel; for production work use a torque-controlled driver.
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.
Common Applications for M10 Socket Set Screws
M10 Socket Set Screws are commonly specified for machine assembly, general engineering, plant maintenance and OEM equipment.
Installation Tips for M10 Socket Set Screws
- Use a quality Allen key fully seated in the socket — partial engagement is the most common cause of stripped sockets at this size.
- For countersunk and button-head variants, chamfer the through-hole to seat the head flush without preloading the head/shank fillet.
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.
