Powertite®
Next generation 
thread-forming

For over 40 years the manufacturing industry has implemented thread-forming TRILOBULAR® screws. Such screws are distinctive for low thread-forming torque and excellent process reliability. For many years thread-forming screws with round cross section have likewise been used. These screws generate higher load capacities, but when it comes to thread-forming they offer less process reliability. 

The recently developed Powertite® screw combines the individual strengths of TRILOBULAR® and round screws to create a high load-bearing, process reliable unit.

Cutting 
costs

Climate 
friendly

Reducing 
weight

The Powertite® screw is a round thread-forming screw with a polygonal tapping tip and can be used in steel, aluminum and other lightweight metals. Tapped nut thread has increased load-bearing capacity > 20% compared with TRILOBULAR® screws.
