M10 is one of the standard coarse-thread sizes for slotted headless screws with shank under ISO 2342. 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 2342)
| Size | Pitch P (mm) | b (mm) | d_s_min (mm) | d_s_max (mm) | n_nom (mm) | n_min (mm) | n_max (mm) | t_min (mm) | t_max (mm) | x_max (mm) | Length range l (mm) | Reference standard |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| M10 | 1.5 | 12 | 9.78 | 10 | 1.6 | 1.66 | 1.91 | 3.75 | 4.25 | 3.8 | 16~35 | ISO 2342 |
Spanner & Drive for M10 Slotted Headless Screws with Shank
The hex socket for M10 Slotted Headless Screws with Shank is shown in the spec table — use the matching Allen / hex key (an ISO 2936 hex key set covers the full range). Ball-end keys are for reaching the screw, not for tightening it — finish on the plain end, and on production work use 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 Headless Screws with Shank Weight
A steel M10 slotted headless screws with shank at the listed 1,635 mm length weighs approximately 1,008 g each — about 1,008 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 Headless Screws with Shank
- 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.
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.
Custom manufacturing · Made to drawing
Need slotted headless screws with shank in a size this table does not list?
This page covers M10 slotted headless screws with shank. Material and finish are usually what drives a special — a grade the standard part is not stocked in, or a coating chosen against a salt-spray figure instead of a default. Made by cold heading or warm forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
