M10 is one of the standard coarse-thread sizes for hexalobular socket cheese head screws under ISO 14580. The sections below reproduce the dimensional row, list the matching tools and hole sizes, and summarize where this size is normally specified.
M10 Dimensional Row (ISO 14580)
| Size | Pitch P (mm) | a (mm) | b (mm) | Head diameter dk (mm) | dk_mean (mm) | da (mm) | Head height k (mm) | n_min (mm) | r (mm) | t_min (mm) | x (mm) | Length range l (mm) | Reference standard |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| M10 | 1.5 | 3.0 | 38.0 | 16.0 | 15.85 | 11.2 | 6.0 | 2.56 | 0.4 | 2.4 | 3.8 | 12~80 | ISO 14580 |
Spanner & Drive for M10 Hexalobular Socket Cheese Head Screws
Drive geometry for M10 Hexalobular Socket Cheese Head Screws is given by the row above; match the tool to the listed values.
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) | ≈ 48 Nm |
|---|---|
| Class 10.9 (dry, ~µ 0.125) | ≈ 71 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 724) | 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 load, class 8.8 | 46 kN |
Proof load = tensile stress area × the proof stress Sp of the class, per ISO 898-1 — Sp is a lower figure than the yield stress Rp0.2 and the two are not interchangeable. The stress area is computed from this size's own diameter and pitch, so a fine-pitch designation gives the fine-pitch figure. Design the joint so the working preload stays below the proof load of the class selected.
M10 Hexalobular Socket Cheese Head Screws Weight
A steel M10 hexalobular socket cheese head screws at the listed 1,280 mm length weighs approximately 2,020 g each — about 2,020 kg per 1,000 pieces. Stainless A2/A4 weighs roughly the same (density 7.9–8.0 g/cm³).
Actual weight varies slightly with head form, thread and finish; use this figure for freight estimation only.
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.
Custom manufacturing · Made to drawing
Need hexalobular socket cheese head screws in a size this table does not list?
This page covers M10 hexalobular socket cheese head screws. Head form and drive can be specified to the assembly rather than to a standard: a larger bearing face, a security drive, or a socket sized for the tool already on the bench. Made by cold heading or warm forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
