M10 Hex Head Bolt — GB/T 5782 / ISO 4014 (Series 001) is the m10-thread variant of Hex Head Bolt — GB/T 5782 / ISO 4014 (Series 001) manufactured to GB/T 5782 / ISO 4014. 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 5782 / ISO 4014)
| Size | Pitch (mm) | Nominal diameter d (mm) | Length L (mm) | Width across flats s (mm) | Width across corners e (mm) | Head height k (mm) |
|---|---|---|---|---|---|---|
| M10 | 1.5 | 10 | 60 | 16.0 | 17.77 | 6.4 |
Spanner & Drive for M10 Hex Head Bolt — GB/T 5782 / ISO 4014 (Series 001)
M10 Hex Head Bolt — GB/T 5782 / ISO 4014 (Series 001) have a width across flats of 16.0 mm — fit a 16.0 mm open-ended spanner or socket. Use a 6-point socket for tight clearances and to reduce rounding; for repeated assembly choose a torque wrench so the joint preload is repeatable.
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 Hex Head Bolt — GB/T 5782 / ISO 4014 (Series 001)
M10 Hex Head Bolt — GB/T 5782 / ISO 4014 (Series 001) are commonly specified for general-purpose machinery, jigs, fixturing and light structural connections.
Installation Tips for M10 Hex Head Bolt — GB/T 5782 / ISO 4014 (Series 001)
- Use a 6-point socket where access allows — 12-point sockets are more prone to rounding the corners on smaller sizes.
- On flanged or serrated variants, do NOT add a separate flat washer — the flange already spreads the load and the washer can defeat the locking serrations.
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.
