SPIRALOCK

Spiralock Technology:

The Edge is in the Wedge

Spiralock is one of three Optia® anti-vibration technologies. By adding a 30° wedge ramp at the root of the internal thread, Spiralock has engineered a simple yet effective way to transform a traditional threaded joint into a safer and more reliable element. This remarkable design provides exceptional resistance to vibration loosening, improved joint integrity and consistent, repeated reusability while eliminating the need for secondary locking devices.
