Product Description

The revolutionary breakthrough of the Two fold self locking small washers lies in the fact that it shifts the source of resistance to vibration from the traditional friction force to a more reliable tension.

（1）Core method: Geometric locking + Mechanical transformation

（2）Energy utilization: Leveraging force: Absorb the vibration energy and convert it into beneficial tension

（3）Key technical parameters: α > β (Wedge angle > Thread rise angle)

（4）Dynamic failure threshold: Extremely high - The greater the vibration, the tighter the locking

（5）Clamping force retention ability: Maintain or enhance

（6）Lubrication/oil contamination impact: Not affected at all

FAQ

（1）Can it be used in combination with other anti-loosening methods (such as anti-loosening nuts)?

No, it is strongly recommended not to use them together. The tension of the Two fold self locking small washers and the friction of the anti-loosening nut will conflict with each other, interfering with normal operation.

（2）What are the requirements for the surface of the connected component?

The surface must be flat, smooth, and its hardness must not exceed that of the washer.

（3）Why does lubrication not affect the anti-loosening effect?

Because tension anti-loosening does not rely on the friction force generated by the contact surface. Even if there is oil contamination, it can still operate normally and achieve the anti-loosening function.

The advantages of Tension anti-loosening

Let me introduce the advantages of the Two fold self locking small washers tension anti-loosening.

（1）The "increasingly tighter" positive feedback: The vibration energy is intelligently converted by the system into locking force, without simple consumption.

（2）Extreme stability under extreme conditions: The anti-loosening performance of the Two fold self locking small washers is completely unaffected by lubrication, oil contamination, temperature fluctuations or corrosion. It can maintain an absolutely consistent locking effect in any harsh working environment.

（3）Extremely high dynamic failure threshold: This directly eliminates the risk of failure of traditional friction gaskets due to material wear or viscosity reduction, significantly extending the maintenance cycle.

（4）Reliable reusability: The tension release function is entirely dependent on the geometric shape, rather than the material deformation.

（5）Long-lasting clamping force retention: Even after prolonged use or in environments with extreme vibrations, the Two fold self locking small washers can still maintain a stable clamping load.
