Dimensional and assembly data for M10 Slotted Set Screws with Cone Point to ISO 7434. Includes head size and width across flats, clearance-hole and tapping-drill diameters, tightening torque per property class, and the sizes to step up or down to when the joint requires it.
M10 Dimensional Row (ISO 7434)
| Size | dt_max (mm) | n_nom (mm) | n_min (mm) | n_max (mm) | t_nom_min (mm) | t_max (mm) | Length range l (mm) | Reference standard |
|---|---|---|---|---|---|---|---|---|
| M10 | 2.5 | 1.6 | 1.66 | 1.91 | 2.4 | 3 | 12~50 | ISO 7434 |
Spanner & Drive for M10 Slotted Set Screws with Cone Point
The hex socket for M10 Slotted Set Screws with Cone Point is shown in the spec table — use the matching Allen / hex key (an ISO 2936 hex key set covers the full range). For a one-off, a T-handle key and a calibrated arm will do. For a batch, the only way to get the same preload twice is 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) | ≈ 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
Set screws are rated to ISO 898-5 by hardness, because they work in compression against a shaft rather than in tension. ISO 898-1 excludes them, and a set screw has no head to preload against, so neither a property class nor a preload torque applies. Seating torque depends on the point form and the shaft material.
M10 Slotted Set Screws with Cone Point Weight
A steel M10 slotted set screws with cone point at the listed 1,250 mm length weighs approximately 771 g each — about 771 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.
Installation Tips for M10 Slotted Set Screws with Cone Point
- 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.
