POWERLOK® screw is the solution for your loosening problems on tapped holes and reduces in-place fastening costs.
TRILOBULAR® POWERLOK®screw for metal is a unique locking concept solution for tapped holes: the thread design provides a locking action over its entire length, regardless of the fastened materials and operating temperatures.
The innovative Dual-Angle™ thread form provides “live-action” locking.
It interferes with the root of the nut thread, which removes any tolerance.
To ensure the correct screw performance, the screw’s hardness must be greater than the nut's.
We recommend contacting our technical department to ensure the suitability of POWERLOK® screws for your application.
Apart from the references available in stock, we produce customized screws to fit your exact requirements.
To improve their functionality, POWERLOK® screws can be produced with different head types, recess, dimensions and coating configurations.
