HARDLOCK Nut provides self locking performance even in the environments
For fail-safe fastening in high-vibration environments, rely on HARDLOCK Nuts (HLN) to surpass your expectations.
Bolted joint loosening typically results from a decrease in initial clamp load due to external factors like impact and vibration. To address this issue, it’s essential to eliminate any play or gap between the bolt and nut threads.
Play will lead to not only shortened life span but also bolt brakeage which can result in catastrophic accidents.
We hit on the idea of utilizing the wedge principle, widely used in ancient Japanese architecture.
Thanks to its principle-inspired design, HLN eliminates thread play completely and outlasts any other nuts in the world when it comes to withstanding severe vibrations.
HLN comprises two nuts: the first, “Convex Nut” or clamping nut, features an eccentric protrusion on its upper surface. When you tighten the Concave Nut onto the Convex Nut, it exerts a robust perpendicular load on the bolt from both sides, effectively securing the HLN and providing resistance to vibrations and impacts from any direction.
After installing HLN you will realize a significant decrease in maintenance related work due to its exceptional self locking effect.
This will offer improvement of running cost, though HLN is a high end product, in combination with the advantage that it can be reused multiple times without almost any decrease in performance.
HLN consists solely of metal, unlike typical self-locking nuts, and comes in a variety of materials and surface treatments suitable for any environment.
HLN is predominantly used in applications which require safety at higher level in extreme conditions and environments, including but not limited to; Railway, Mining, Civil engineering and Machinery, just to name a few.
