What role does a flat washer play in a fastener?

Flat washers are also called flat washers. They are mainly stamped out of iron plates. They are generally round or square in shape with a hole in the middle. The size of this hole generally corresponds to the bolt diameter and can also be made according to customer requirements.

Normally, the flat washers suitable for bolts of the same specification have the same aperture, but different outer diameters and thicknesses. For example, the flat washer aperture used for M10 bolts is 10mm, and the outer diameter and thickness are not fixed. Galvanized flat washers Flat washers are often used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. This component is found in many materials and structures to perform various similar functions. Due to the material and process limitations of threaded fasteners, the bearing surface of fasteners such as bolts is not large. Therefore, in order to reduce the compressive stress of the pressure-bearing surface and protect the surface of the connected parts, bolts are often equipped with flat washers when used. Therefore, flat washers are essential auxiliary accessories in bolt fasteners.

304 stainless steel flat washers are made of different materials according to the pressure limit and the use environment.

Commonly used flat washers are made of iron, carbon steel, stainless steel, copper, plastic, etc. The sizes of flat washers are generally divided into standard size, enlarged, thickened, enlarged and thickened, etc.
