The (M14) size of Cap Nuts, GOST 11860 Type 1 is dimensioned by GOST 11860. The table below gives the dimensional row from the standard, followed by the drive and the installation notes for this type.
Values are taken from the governing standard rather than from a general machine-thread table, because this type is not selected on one.

| Size | Pitch P (mm) | dk (mm) | h (mm) | Nut height m (mm) | Width across flats s (mm) | t (mm) | w (mm) | Reference standard |
|---|
| (M14) | 2.5 | 20 | 25 | 11 | 21 | 18 | 4 | GOST 11860 |

Service conditions to specify against
- Marine and coastal
- Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
- High load
- Supplied in ISO 898-1 property classes, so the joint can be designed to a stated proof load and tightened to a calculated torque rather than by feel.
- Match the class
- A nut below the bolt property class strips before the bolt reaches its own limit — pair class 8 nuts with 8.8 bolts, class 10 with 10.9.
Where to use something else
- Do not substitute DIN 1587 without checking height.
