Double fold self-locking washer(Steel/Stainless Steel)

Double stacked self-locking anti-loosening heat ring is composed of two pieces in pairs, the outer side with radial slant fine teeth, while the inner side for the slant angle is greater than the shot of the wide tooth surface (washers). The wide tooth angle is greater than the bolt thread angle, and the assembly of the inner oblique tooth surface is relative to the outer radial tooth surface and the two ends of the contact surface into the bite state, when the connector is subjected to vibration and make the bolt tendency to loosen, just allow the two pieces of the inner oblique teeth of the washer to move relative to each other to produce tension lift, so as to achieve one hundred percent of the prevention of looseness.DIN25201 double-stacked self-locking washer is a kind of fastener used for the connection of the It is a special washer with a double-layer design that provides a more reliable connection in vibrating environments. These washers are commonly used in engineering applications such as automotive, machinery, and equipment.    

Features of double stack self-locking washers
RELIABLE SEALING: Double stack self-locking washers consist of two elastic metal rings, which can form a reliable sealing and fixing connection during assembly.
Self-locking function: When torque is applied to the connecting bolt, the wavy teeth of the double-stacked self-locking washers will start to deform, which increases the connecting torque and makes the connection more solid and stable.
Repeated use: Double-stacked self-locking washers can be used repeatedly and have a long service life.
Anti-loosening: Double stack self-locking washers can effectively prevent the connection from loosening, avoiding mechanical equipment failure and safety accidents.
High-temperature and corrosion resistance: Double-stacked self-locking washers are usually made of high-temperature and corrosion-resistant materials, which can adapt to different working environments.
