How do POWERLOK® screws work?

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.
