The M14 size of Wheel Nuts, Conical and Ball Seat is dimensioned by Trade series (wheel nut). 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.
M14 Dimensional Row (Trade series (wheel nut))
| Thread size | Pitch (mm) | Seat type | Width across flats s (mm) | Total height m (mm) | Typical torque (Nm) | Material | Finish |
|---|---|---|---|---|---|---|---|
| M14 | 1.5 | Conical 60° | 19 | 24 | 140 | Class 10 steel | Zinc / chrome cap |
Spanner & Drive for M14 Wheel Nuts, Conical and Ball Seat
Drive geometry for M14 Wheel Nuts, Conical and Ball Seat is given by the row above; match the tool to the listed values.
Tightening Torque for M14
| Class 8.8 (dry, ~µ 0.125) | ≈ 145 Nm |
|---|---|
| Class 10.9 (dry, ~µ 0.125) | ≈ 213 Nm |
| Class 12.9 (dry, ~µ 0.125) | ≈ 249 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 M14
Nuts are graded to ISO 898-2 by the proof load the nut itself will hold (classes 04, 05, 5, 6, 8, 10 and 12), not by the 8.8 / 10.9 / 12.9 scale used for bolts. A class-8 nut is the correct mate for a class-8.8 bolt, and the joint is designed on the bolt, so no bolt-tension figure is quoted here.
Mating Parts for M14
Pair M14 with the matching M14 bolt or screw, plus a M14 flat washer where required to distribute load on softer materials.
