Countersunk head rivet RIVSET®

Joining of aluminium cast with new ring groove die While joining steel and/or aluminium sheets on cast aluminium material by using self-pierce riveting technology with semi-tubular rivets, cracking can occur in the material on the button side. This is caused by the mechanical characteristics of the cast material. The new RIVSET® ring groove die, made by Böllhoff, minimises cracking and ensures an increased interlock as well as reduced rivet load. Your benefits - Avoidance/minimisation of cracking on the button side - Reduced rivet load due to an optional cup - Increased interlock of the rivet by controlling material movement in the die
