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 video is a demonstration between a standard fastener and a revolutionary Spiralock fastener at 15 kilonewtons tension. After just 20 seconds the standard fastener has completely loosened.
