POWERLOK® II™ Fastener Geometry
Thread Profile:
The innovative Dual-Angle™ thread form provides “live-action” locking.
The deflection of the thread tip creates classic “stored energy” locking.
Interferes in the root of the nut thread. Locking is not affected by an incomplete internal thread form.
TRILOBULAR® Body:
Capitalizes on elastic memory of nut member.
Further, it prevents vibrational loosening by providing additional locking action.
Reduces friction during installation.
POWERLOK® II™ Fastener Advantages
- No need for patches, adhesives, or assembly line-applied locking compounds.
- Locking action is over the entire length of the screw thread.
- Locking action is not affected by temperature.
- No adhesive curing time—instantaneous locking action.
- No need for underhead locking elements.
- No need for costly lock washers.
- Works with all finishes.
- Easily hand-started.
