About This Product

Product information

■Better locking effect than spring washers and toothed washers

Polywave is made by bending the seat of the screw head at an angle, making it wave-like, and applying heat treatment to give it elasticity and hardness, so the screw head itself is stronger than spring washers and toothed washers. play a role.

■Returning torque increases relative to tightening torque

Polywave is not only much more effective than any type of washer to prevent loosening, but the return torque actually increases compared to the tightening torque. The reason is that by tightening Polywave, the wavy seating surface of Polywave elastically adheres to the object to be tightened, and at the same time, the wavy convex portions bite into the object while applying plastic deformation. . After tightening is completed, the polywave rotates by itself due to vibration, but the convex part that has bitten into the object to be tightened bites even deeper, which increases the return torque and prevents loosening. Gives a big effect.

■Improvement of work efficiency

PolyWave has an integrated screw and washer structure, which reduces assembly man-hours and improves work efficiency.

■Simplification of operations

Using Polywave eliminates the need for washers, which saves time and effort from ordering to inventory management, helping to simplify your business. product structure

■Material, heat treatment and surface treatment

The material is carburized, quenched and tempered low carbon steel, and the surface treatment can be zinc plating, nickel plating, chrome plating, etc.
