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.

Carbon steel/alloy steel automotive Car Wheel Bolts, classified according to strength grades 8.8/10.9/12.9, provide 60 ° conical, spherical, and planar contact types. The keyway and wheel hub hole are fitted with interference fit for precise positioning. Suitable for passenger cars, light trucks, and heavy trucks, high-strength material selection, anti loosening and rust prevention, stable and reliable road testing.

The DIN557 stainless steel square nuts are made of A2 or A4 stainless steel and possess excellent corrosion resistance. Their square structure is specifically designed for anti-turning and slot rail installation, enabling them to effectively fit into the T-shaped slots of industrial aluminum profiles or the edges of structures, preventing slippage during tightening. They are particularly suitable for frame assembly, welding structures, and single-side operation scenarios. The specifications range from M5 to M16. They are an efficient fastening solution for mechanical equipment, racks, and general industrial connections.

304 stainless steel hex head screw with column, featuring a hexagonal slot and a central anti-tamper post. It can only be driven with a specialized hollow hex bit; standard Allen wrenches, flathead, or Phillips screwdrivers cannot fit. Designed for use in equipment requiring anti-tampering and anti-disassembly protection.

Flat Thin Head Screw has a flat head that is almost parallel to the workpiece after tightening. It has been treated with blackening, matte black, and does not reflect light. It is suitable for installation inside equipment or on external components. Cross groove drive for quick locking.
