How does it work?
The HARDLOCK Nut adopts the wedge principle to create its locking force. Initially, the lower convex nut applies axial torque akin to a regular nut. Notably, this nut incorporates a slight eccentricity at its upper convex part (highlighted in red). Subsequently, upon tightening the symmetrical upper concave lock nut against this eccentricity, it creates a perpendicular wedge effect relative to the axis. This action forces the lower convex nut firmly against the screw thread, establishing a resilient self-locking force, rendering it impervious to external vibrations or impacts.
Its proven reliability enables its users to benefit from a significant reduction in their maintenance costs. What’s more, the Hardlock Nut is reusable. Tested to 50 cycles, with no loss of performance!
The versatile HARDLOCK Nut is available in a range of sizes, thread types, and can be retrofitted to existing male thread components when required.
