Product Description

The core advantage of the Double Fold self locking large washers lies in its adoption of the tension anti-loosening principle, which has perfectly solved the problem that traditional anti-loosening methods are prone to failure under intense vibration.

（1）From friction-based anti-loosening to tension-based anti-loosening innovations

（2）Top-notch anti-loosening performance: Compared to traditional solutions, the Double Fold self locking large washers can offer the highest level of safety, ensuring that the connection remains stable even under extreme vibrations and impacts.

（3）Stable working condition: The locking effect is not affected by lubrication or oil contamination, and it can provide a stable locking effect.

（4）Installation and maintenance are convenient: Installation and disassembly can be completed using standard tools.

（5）Reusability: After normal installation and disassembly, there will be no permanent deformation, and it can be reused multiple times.

（6）Reduce overall costs: Significantly reduced maintenance costs, avoiding high repair expenses and potential safety hazards.

（7）Geometric locking: Without the use of any chemical adhesives, it is a purely mechanical interlocking mechanism.

Application

The following are some of the core application scenarios of Double Fold self locking large washers:

（1）Wind Power

In the difficult high-altitude operations, the Double Fold self locking large washers uses the tension locking principle to make the nut "tighten more and more" through vibration, effectively solving the problem of loosening of the fan bolts.

（2）Power Generation

In areas with high vibration and high heat such as gas turbines, hydro turbines, steam turbines and nuclear island equipment, gaskets can prevent losses caused by thermal expansion and contraction.

（3）Agri & Forestry

During agricultural machinery operations, there may be intense vibrations. Using Double Fold self locking large washers can reduce the loss of "agricultural time" or "working time" caused by maintenance shutdowns.
