POWERLOK® screws

Prevent vibrational loosening in tapped holes without additional locking elements

When to choose POWERLOK® screw?

TRILOBULAR^® POWERLOK^® screws are recommended to solve loosening problems in tapped holes, specially in the assembly of components under severe vibration conditions and expansion/contraction cycles.

POWERLOK^® screws eliminate the need of additional locking elements, such as adhesive patches, locking washers and locking nuts.

How does it work?

TRILOBULAR^® POWERLOK^® screw for metal is a unique locking concept solution for tapped holes:

The innovative Dual-Angle™ thread form provides “live-action” locking over its entire length, regardless of the fastened materials and operating temperatures.
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.
