M10 Phillips Pan Head Machine Screw — GB/T 818 / ISO 7045 (Series 034) is the m10-thread variant of Phillips Pan Head Machine Screw — GB/T 818 / ISO 7045 (Series 034) manufactured to GB/T 818 / ISO 7045. This page focuses on the data engineers reach for at the bench: dimensional values for the M10 size, the spanner/drive that fits, and the assembly data you need to install it.
M10 Dimensional Row (GB/T 818 / ISO 7045)
| Size | Pitch (mm) | Length L (mm) | Head diameter dk (mm) | Head height k (mm) | Cross recess | Reference standard |
|---|---|---|---|---|---|---|
| M10 | 1.5 | 60 | 20.0 | 6.0 | PH4 | ISO 7045 / GB/T 818 |
Spanner & Drive for M10 Phillips Pan Head Machine Screw — GB/T 818 / ISO 7045 (Series 034)
M10 Phillips Pan Head Machine Screw — GB/T 818 / ISO 7045 (Series 034) 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.
Common Applications for M10 Phillips Pan Head Machine Screw — GB/T 818 / ISO 7045 (Series 034)
M10 Phillips Pan Head Machine Screw — GB/T 818 / ISO 7045 (Series 034) are commonly specified for machine assembly, general engineering, plant maintenance and OEM equipment.
Installation Tips for M10 Phillips Pan Head Machine Screw — GB/T 818 / ISO 7045 (Series 034)
- 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.
