M2.5 Self-Clinching Threaded Studs and Pins are manufactured to Trade series (self-clinching studs and pins). This page lists the controlling dimensions for the M2.5 size together with 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.
M2.5 Dimensional Row (Trade series (self-clinching studs and pins))
| Thread size | Length options (mm) | Head form | Material options | Example installation hole (mm) | Example sheet thickness (mm) | Example pull-through (N) |
|---|---|---|---|---|---|---|
| M2.5 | 6 / 8 / 12 / 18 | flush-head stud | steel / stainless steel / aluminum | 2.5 | 1.0~1.95 | 2600 at 1.6 mm aluminum; 2800 at 1.5 mm steel |
Spanner & Drive for M2.5 Self-Clinching Threaded Studs and Pins
Drive geometry for M2.5 Self-Clinching Threaded Studs and Pins is given by the row above; match the tool to the listed values.
Tightening Torque for M2.5
| Class 8.8 (dry, ~µ 0.125) | ≈ 0.7 Nm |
|---|---|
| Class 10.9 (dry, ~µ 0.125) | ≈ Nm |
| Class 12.9 (dry, ~µ 0.125) | ≈ 1.2 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 M2.5
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.
Installation Tips for M2.5 Self-Clinching Threaded Studs and Pins
- At M2.5 the joint is sensitive to over-torque — use a torque-limiting driver and check the head doesn't bury into a softer counterpart.
Mating Parts for M2.5
Pair M2.5 with the matching M2.5 bolt or screw, plus a M2.5 flat washer where required to distribute load on softer materials.
