Spiralock® Self-Locking Threaded Solutions

Clarendon Specialty Fasteners provides a comprehensive range of Spiralock® taps, gauges and locknuts:

  • Taps & 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.
  • 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.
