TriPress® Nut
Maximum performance with minimum press-in force

TriPress® nut – the reliable solution for modern multi-material designs. At a time when components are becoming increasingly complex and a wide variety of materials are being used, fasteners that are flexible and high-performance are needed. The TriPress® nut was developed precisely for this purpose. It is ideal for steel or aluminum sheets as well as for cast components made of magnesium or aluminum – even with a material thickness of just 2.8 mm.

Cutting 
costs

Fast
assembly

Versatile 
application

Thanks to its specially developed trilobular knurled geometry, it can be securely inserted into laser-cut, punched, or cast pilot holes with very little pressing force. This ensures a material-friendly, reliable, and high-strength connection.
