The Solution
The Hardlock Nut, designed to be simple, robust, re-useable and more effective at resisting loosening by shock & vibration than any other locking nut.
The Hardlock uses a mechanical principle that makes it unique. This is how it works:
The Hardlock functions by utilising two nuts that work together. The cone on the lower nut is off-set, so that when tightened against the upper nut, vertical and horizontal locking forces engage the screw thread.
