The HONSEL “HOCHFEST” technology allows a significant increase in the load-bearing strength of the thread. This ensures that in the event of mechanical overloading, a bolt of strength class 12.9 (“HOCHFEST” steel) or 8.8 (“HOCHFEST” aluminium) fails far earlier than the HONSEL blind rivet nut.

This ensures greater safety in all applications where higher mechanical demands are necessary.

„HOCHFEST“ steel
