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.

Stainless steel square flat pad, with an additional pressure bearing surface at the four corners compared to the circular gasket. Used on square tubes, channel steel, or wooden surfaces, the gasket will not rotate with the screw, making it more stable under stress. Made of 304 stainless steel material, it is rust resistant and non corrosive. Sizes range from M3 to M20, with a thickness of 1mm to 3mm, and can be customized even if required.

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.

Jinghong Manufacturer specializes in providing ISO 7091 Flat Washers, which are made from high-quality carbon steel and stainless steel, with a product grade of Class C. These washers are suitable for use with bolts and nuts to distribute pressure, protect workpiece surfaces, and prevent loosening. They are widely used in various maintenance fields such as building structures.

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.
