A nut that does not loosen even after 1 million vibration tests (3D vertical and horizontal)! Compatible bolt sizes: M14 to M100.
■ Structure and Non-Loosening Principle of the Strongest Lock Nut "Bolrock Nut"
1. When the nut is subjected to vibration and attempts to loosen counterclockwise, the fine internal balls utilize a clutch mechanism to exhibit a wedging effect, preventing the nut from turning and loosening.
2. The slope angle of the internal balls is designed to be larger than the "screw lead angle," which is the angle at which the screw rises one full turn.
3. When the nut is tightened, the internal balls automatically move to the deepest part of the groove, aligning the bottom of the nut with the top of the balls, eliminating any gap between them and the floor, thus not affecting the tightening axial force.
■ Vibration Test Condition Data
- Bolt Diameter: M16
- Bolt and Nut Material: SCM435
- Frequency: 100Hz
- Number of Vibrations: 1,000,000 times
- Simultaneous 3D vibration in both vertical and horizontal directions
While competitor lock nuts loosen after 1,100 to 2,300 vibrations, the Plarad Bolrock Nut withstands 1,000,000 vibrations, proving its overwhelming vibration resistance.
