The allrounder for your production.


Flexible and efficient

It allows the joining of high-strength steels up to ultrahigh-strength steels (> 1,500 MPa) with dissimilar materials such as aluminium.

This flexibility is primarily achieved through the conical hole geometry. In combination with the hole bottom with optimised flux of force, the HDZ rivet is so highly stable that already in hardness grade H4 the joining of press-hardened steels is possible.

This product is made by Böllhoff
