TriPress®
Reduces assembly time by up to 75%

This triangular rapid fastener system from ARNOLD can be pressed into plastics, light metals and steel to join two components quickly and economically. The triangular shape allows torsion torques which, compared with bolts with round knurls are around 35% higher – and also present higher vibration resistance, They are also particularly secure when fitting nuts with the TriPress® centre collar version (MB) and the TriPress® connecting fastener.
