Wedge Lock Washers.
These two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting. Washers are reusable.
Zinc-flake-coated steel washers are corrosion resistant in wet environments.316 stainless steel and zinc-flake-coated steel washers are comparable to Series washers.Spring lock washers are comparable to washers. They withstand vibration better than standard wedge lock washers by combining the locking power of a wedge lock with the clamping force of a spring lock.
DIN25201 Double fold self-locking washer（Steel/Stainless Steel）Mainly used in the automobile industry, railway bridge, construction engineering, agricultural machinery, machinery industry, machine tool equipment, mold, equipment, reducer, gearbox, and a series of products.
Reliable seal: The double-stack self-locking washer consists of two elastic metal rings that form a reliable seal and secure connection when assembled.
1. Self-locking function: When torque is applied to the connection bolt, the wavy teeth of the double-stack self-locking washer will begin to deform, thereby increasing the connection torque and making the connection more stable.
2. Reuse: double-stack self-locking gaskets can be used repeatedly and have a long service life.
3. Anti-loosening: the double-stack self-locking washer can effectively prevent the loosening of the connection and avoid the occurrence of mechanical equipment failure and safety accidents.
4. High temperature and corrosion resistance: Double stack self-locking gaskets are usually made of high temperature and corrosion resistant materials, which can adapt to different working environments.
