Finexpress Dacromet Washer GB/T 95 The surface of the gasket is treated with Dacromet to have strong corrosion resistance and is mostly used in outdoor power towers and other equipment. Flat washers are usually thin pieces of various shapes, used to prevent leakage, reduce friction, prevent loosening, separation or disperse pressure. Many mechanical structures or installations have such parts, which are used to perform various similar functions. Due to the process and material limitations of threaded fasteners, the bearing surface of fasteners such as bolts is not large, so washers are used to reduce the compressive stress of the pressure-bearing surface and protect the surface of the connected parts.
Light spring washers GB/T 859-1987 Spring washers are installed under nuts to prevent them from loosening. In the screw industry, spring washers are often called spring washers. They are made of stainless steel and carbon steel, which is iron. Commonly used spring washers are M3, M4, M5, M6, M8, M10. M12, M14, and M16. These specifications are more commonly used.
