POWERLOK® Thread-Locking Screws
POWERLOK®
Thread-Locking Screws
POWERLOK®
POWERLOK® thread-locking fasteners lower the cost of assembly through the elimination of parts and process steps, as well as through direct and indirect
costs. POWERLOK® screws provide exceptional resistance to vibrational loosening through the creation of physical interference in the root of the nut
member. This interference eliminates the need for expensive physical and chemical locking solutions. Eliminating the use of chemical adhesives or patches simplifies processes and procurement and also reduces environmental impact.
The features and benefits of the POWERLOK® fastener are “rolled on” as the fastener is made in the heading and rolling process. This makes POWERLOK® thread-locking fasteners highly cost-effective compared to fastening solutions requiring secondary operations.
Most importantly, POWERLOK® fasteners provide superior performance to available alternatives in applications where resistance to vibrational loosening is mandatory, as well as in electrical grounding applications. POWERLOK® fasteners’ ability to lock without pre-tensioning also makes them an excellent choice as an adjusting and clamping screw.
POWERLOK® fasteners are used across a broad range of applications as a high-performance and cost-effective solution.
The Original TRILOBULAR® Locking Fastener
The first screw in the POWERLOK® family, the original POWERLOK® fastener paved the way for consistent mechanical interference locking in the nut member.

POWERLOK® II™
All Metal Locking Fasteners
POWERLOK® II™ fasteners are the most advanced all metal locking screw on the market. Featuring a TRILOBULAR® cross-section and a patented Dual-Angle™ thread form, the screw is optimized to provide maximum resistance to vibration and mechanical loosening under a range of temperatures and environmental conditions where chemical adhesives and patches would fail.
Features
-
Improved, innovative Dual-Angle™ thread profile provides consistent, positive locking action
-
Dual-Angle™ thread tip deflection also provides a spring-like stored energy locking
-
Mechanically interferes in the root of the nut thread, and is unaffected by any incomplete internal thread-forming
