The (M14) size of Low Head Socket Cap Screws is dimensioned by DIN 7984. The tables below give the dimensional row from the standard, the drill and spanner sizes that go with it, and the assembly torque per property class. The technical drawing on this page redraws to the exact values selected.
(M14) Dimensional Row (DIN 7984)
| Size | Pitch P (mm) | b (mm) | Head diameter dk (mm) | da (mm) | ds_min (mm) | e (mm) | Head height k (mm) | r (mm) | Hex socket s (mm) | t (mm) | v (mm) | dw (mm) | Length range l (mm) | Reference standard |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| (M14) | 2.0 | 34 | 21.0 | 15.7 | 13.73 | 11.43 | 8.0 | 0.6 | 10.0 | 5.3 | 1.4 | 19.83 | 30~80 | DIN 7984 |
Spanner & Drive for (M14) Low Head Socket Cap Screws
The hex socket for (M14) Low Head Socket Cap Screws 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.
(M14) Low Head Socket Cap Screws Weight
A steel (M14) low head socket cap screws at the listed 3,080 mm length weighs approximately 8,374 g each — about 8,374 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 (M14) Low Head Socket Cap Screws
- 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 (M14)
For (M14), pair with a (M14) hex nut (ISO 4032 / DIN 934) and, where used, a (M14) flat washer (ISO 7089 / DIN 125A) under the head and under the nut.
