What is Spiralock?
Spiralock is a unique, proprietary, preload locking internal (female) thread form. It is exceptionally resistant to the effects of vibration loosening and substantially reduces the potential of fatigue failure when compared to standard, symmetrical thread forms. Spiralock does not require any of the secondary methods (e.g., lock washers, thread adhesives, crimping, inserts, etc.); rather, it relies entirely on the unique geometry of its thread form.
