To effectively utilize the wedge structure, two nuts are used: (1) a convex nut with an eccentrically formed boss, and (2) a perfectly circular concave nut. When these nuts are fastened together, the wedge principle mechanically creates a powerful locking effect transverse to the bolt shaft. This powerful anti-loosening effect achieved with the HLN Hardlock Nut wedge completely fuses the bolt and nut. Once locked with this powerful force, the HLN Hardlock Nut is not susceptible to impulsive forces or shocks.
Leveraging the power of the wedge principle, the HLN Hardlock Nut is the ultimate self-locking nut which completely integrates the nut and the bolt. It passes United States NAS (National Aerospace Standard) aviation standards, features torque and axial force control and can be easily installed with just one commercially available tool.
At the booth on the 2nd floor of the MOBIO Tech Hall, HARDLOCK displays HLN Hardlock Nuts and HLB Hardlock Bearing Nuts.
