Wedge-Lock Dual-Layer Washers are manufactured from high-hardness alloy steel and feature a unique internal and external serrated design. Utilizing the principle of tension rather than friction, they counteract loosening caused by extreme vibration. The surface is treated with high-performance anti-corrosion coating, providing powerful locking force without damaging the mating components, ensuring permanent fastening under extreme impact conditions.
Extensively utilized in rail transit, wind power generation, heavy mining machinery, and automotive chassis systems. They are particularly ideal for critical joints subjected to high-frequency vibration, alternating loads, or thermal fluctuations that cause conventional fasteners to loosen, meeting the stringent safety standards of heavy equipment manufacturing.
