On the bench specifying M10 Hex Bolt — GB/T 5783 / ISO 4017 (Series 010)? This page gives the controlling dimensions for the M10 size of Hex Bolt — GB/T 5783 / ISO 4017 (Series 010) (to GB/T 5783 / ISO 4017).
M10 Dimensional Row (GB/T 5783 / ISO 4017)
| 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 Bolt — GB/T 5783 / ISO 4017 (Series 010)
M10 Hex Bolt — GB/T 5783 / ISO 4017 (Series 010) 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 Bolt — GB/T 5783 / ISO 4017 (Series 010)
M10 Hex Bolt — GB/T 5783 / ISO 4017 (Series 010) are commonly specified for general-purpose machinery, jigs, fixturing and light structural connections.
Mating Parts for M10
For M10, pair with a M10 hex nut (ISO 4032 / DIN 934) and, where used, a M10 flat washer (ISO 7089 / DIN 125A) under the head and under the nut.
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.
