POWERLOK® screws
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.
Benefits

- In-place fastening cost reduction by eliminating the need for additional locking elements, such as adhesive patches, locking washer, etc.
- Excellent vibration loosening resistance. POWERLOK® screw meets the standards of regulation IFI 524.
