About Us

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.
