Spiralock provides Military-Approved Self-Locking Reusable Fasteners featuring a unique internal thread form incorporating a 30° wedge ramp at the root of the thread. Spiralock® is exceptionally resistant to vibration loosening.
Spiralock is a unique and proprietary preload locking internal (female) thread form that's exceptionally resistant to transverse vibration—the primary cause of thread loosening.
Proven in thousands of applications, Spiralock threaded holes and nuts accept standard male fasteners, eliminate the need for other locking devices, and substantially reduce the potential for fatigue failure when compared to standard threads.
