SPIRALOCK Bolts - Effectively solve the problem of loosening
SPIRALOCK is a self-locking thread technology with a unique thread structure design. It has an outstanding ability to resist lateral vibration, thereby fundamentally solving the problem of thread loosening.
At the bottom of the thread of the female thread, there is a 30-degree wedge-shaped inclined surface. When the bolt and nut are tightened against each other, the tip of the bolt thread tightly presses against the wedge-shaped inclined surface of the bolt thread, thereby generating a significant locking force. Due to the change in the Angle of the thread profile, the normal force generated by the contact between the threads forms a 60-degree Angle with the bolt's axis, rather than the 30-degree Angle like that of a common thread. The normal pressure of the screw thread is much greater than the clamping pressure. Therefore, the anti-loosening friction force generated is bound to increase significantly. Meanwhile, when the top of the male thread engages with the SPIRALOCK female thread, the tip of the tooth at the top is prone to deformation, which enables the load to be evenly distributed along the entire length of the contacting helical line. This avoids the phenomenon that over 80% of the total load is concentrated on the thread surfaces of the first and second threads during the engagement of ordinary standard threads. Therefore, the SPIRALOCK threaded connection pair not only overcomes the drawback of the ordinary standard connection pair, which is prone to self-loosening under vibration conditions, but also can extend its service life.
The advantages of the SPIRALOCK thread:
Reliable seismic and anti-loosening performance;
2. It can significantly increase the service life of nuts and bolts;
3. Reusable;
4. It is not affected by drastic temperature changes and has a wide range of application environments.
5. Free-rotating type, torque only needs to be applied when tightened, which is convenient for loading and unloading.
6. There are no restrictions on size specifications.
7. Match with standard external threads;
8. No auxiliary locking components are required, such as spring washers, stop washers, etc.
9. Not only nuts, but also SPIRALOCK taps can be used to produce Spiro screw holes with the same anti-loosening performance, which can be widely used in components that require self-locking functions.
10. It has a remarkable effect on overcoming the problem of teeth slipping caused by soft materials such as aluminum alloy.
