Solve loosening problems on tapped holes and reduce in-place fastening costs.

TRILOBULAR^® POWERLOK^® screw is unique solution with locking concept on tapped holes: the thread design provides locking action over the entire length, independently of the base material and working temperatures.

Advantages of POWERLOK^®screws.

• Immediate and continuous locking action.

• In-place fastening cost reduction by eliminating the need for additional locking elements.

• Excellent vibration loosening resistance.

• The spring effect maintains clamping.

How does POWERLOK^® screws work?

The innovative Dual-Angle™ thread form provides “live-action” locking.

It interferes in the root of the nut thread, eliminating any tolerance.

To ensure a correct performance of the screw, screw hardness values should be higher than nut ones.

We recommend to contact our technical department to assure the feasibility of POWERLOK^® screws in your application.
