Before setting |
- Hole diameter: Hole diameters should be taken from the appropriate product table. The surfaces in the grip range should be parallel +/– 0.05.
- If possible use the preferred hexagonal or knurled RIVNUT® and always:
 Install the RIVNUT® blind rivet nuts and RIVSTUD® blind rivet studs in accordance with our
recommendations (stroke S),
 Ensure that the parts to be joined cannot rotate with respect to one another and that
the gap between the elements to be riveted together is not too large. |  |
 | |
Setting
- We recommend that you use the spin-pull setting technique. With this technique, the RIVNUT® blind nut or RIVSTUD® blind rivet stud is threaded (spun) on to the mandrel, inserted into the hole and then pulled back (without rotation) to upset the rivet nut body. Finally the mandrel is spun out.
Our range of setting tools can be found under rivet tools.
The P803, EPK and PNK setting tools have a pressure monitoring system, which is very useful for components with varying thicknesses (guarantees consistent setting).
Important: Setting several RIVNUT® at the same time can be done using a press. However, we advise you to contact us in advance about this. We would not recommend that you use mechanical screw drivers or spanners for blind riveting as they can damage the surface of the thread and thus have a detrimental effect on your connection.
- Adjusting the stroke
- The product tables from page 14 onwards contain the setting stroke values recommended for optimum setting of each type of RIVNUT® blind rivet nut, e.g.:
RIVNUT® 233 07 060 230, P. 16, S = 5 – e, i.e. for a material thickness of e = 2 mm the RIVNUT® stroke S is adjusted to S = 5 – 2 = 3 mm.
 Note: The stroke is measured on the RIVNUT® (the difference in length before and after setting) and not on the tool.
We recommend that you carry out a trial assembly before starting series production.

After setting
- Maximum dimension of the crimping flange (w)
This applies to RIVNUT®plus and RIVNUT® blind rivet nuts and RIVSTUD® blind rivet studs with the exception of the extra-small countersunk heads type 343 01, 343 08, 343 21.
| Measure RIVNUT® | M3 | M4 | M5 | M6 | M8 | M 10 | M12 |
| Max. crimping flange | | | | | | | |
| dimension (mm) | 6,8 | 8,6 | 10,1 | 13,0 | 15,0 | 18,0 | 22,4 |
- Axial dimensions after setting
The tables on pages 15 to 30 show indicative values of the projecting body length L2 after installation. | |
