China Specialty Washers Manufacturers, Suppliers, Factory

Jinghong Factory specializes in producing Double Layered Self locking Anti Loose Washing, which is made of 304 stainless steel and consists of two pairs of washers with wedge-shaped teeth. The product is locked using the wedging principle and can maintain locking force under severe vibration and temperature changes. It is commonly used in situations with high anti loosening requirements.

DIN 434 galvanized Square Taper Washers for U-sections are standard components specifically designed for bolt connections of channel steel (U-shaped steel). They are made of galvanized carbon steel and automatically compensate for the angle deviation of the channel steel flange through 10°/12° inclined surfaces, converting the axial force of the bolt into radial supporting force, effectively dispersing stress, preventing the channel steel from collapsing, and enhancing the shear resistance of the connection. They are widely used in steel structure projects such as construction, machinery, power, and rail transportation.

SS304 Washers with Ball Face (M6-M48) is made of 304 stainless steel. Its spherical structure can adaptively compensate for the inclination angle of the connection surface (up to approximately 4°), effectively eliminating the bending stress caused by assembly skew and preventing bolt fatigue loosening. It also has excellent corrosion resistance and load dispersion capability, and is widely used in critical structures of heavy machinery, bridges, pipelines, and rail vehicles that require high connection accuracy and rust prevention.

This product is a conical spring washer that complies with the DIN6796 and is made of SS304. It comes in specifications ranging from M3-M30 and is specifically designed for bolted connection structures. It features excellent elasticity, corrosion resistance, and fatigue resistance. It can effectively prevent loosening of fasteners caused by vibration, thermal expansion and contraction, and load changes through continuous elastic preload. It can be used in combination or in layers to meet different preload requirements. The installation is simple and the reliability is high. It is widely used in various mechanical, steel structure and equipment assembly scenarios where there are strict requirements for anti-loosening, vibration resistance and corrosion resistance.

The Lock Washers for 65Mn GOST 11872 round nuts is a multi-tongue locking gasket made of 65Mn spring steel. It is specifically designed for the anti-loosening locking of GOST 11871 round nuts. The core part is used for axial positioning anti-loosening in high-vibration and high-load working conditions. It is a key fastener for mechanical transmission and equipment locking.

Stainless steel internal and external serrated washers (M2-M20) are made of 304 stainless steel. The double-sided serrated structure on the inner and outer edges can simultaneously engage with the bolt and the surface of the workpiece, providing multiple anti-loosening guarantees. They have excellent corrosion resistance and anti-vibration properties, and are suitable for long-term locking requirements in high-load, high-vibration and harsh environments in the automotive, rail transit, power, petrochemical and other fields.
