Locknuts

The unique Spiralock® female thread form with a 30° ramp on its major diameter gives a free running locknut until it is torqued up, the major diameter of the bolt then engages this ramp and provides a secure lock - so secure in fact that it is used in the Space Shuttle engines, medical implants and turbochargers. Not only does it provide far higher reuse than prevailing torque nuts but it also gives consistent preload and better load distribution in the joint.

Taps and Gauges

Eliminate thread locking inserts or adhesives by tapping your own locking threads with the Spiralock® threading system. Apply Spiralock® to castings, structures and components by using Spiralock® taps and threaded forming inserts with their corresponding gauges.
