What is the function of flat washers?

There are many different names for flat washers in the industry, such as meson, washer, and flat washers. The appearance of a flat washer is relatively simple, which is a round iron sheet with a hollow center. This hollow circle is placed on the screw. The manufacturing process of flat washers is also relatively simple. Generally, it is produced by stamping process, which is relatively fast. Generally, dozens of them can be stamped out at a time, and the quantity is determined according to the size of the mold. Therefore, the price of flat washers is relatively cheap.

The larger the specification, the higher the price; secondly, the price is determined according to your requirements for size. If your product requires a very small dimensional tolerance, then the inventory of batch production should not meet the tolerance requirements, so the machine needs to be adjusted and re-produced, so the price will be relatively high; and the customer needs a non-standard flat washer, which needs to be customized by mold opening, so the price will definitely be higher.

Flat washers are often used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure, etc. There are also many materials for flat washers, such as galvanized or blackened carbon steel, stainless steel 304 or 316, brass, etc. Due to the material and process limitations of threaded fasteners, the bearing surface of fasteners such as bolts is not large. In order to reduce the compressive stress of the bearing surface and protect the surface of the connected parts, bolts are often equipped with flat washers when used. Therefore, flat washers are very common auxiliary accessories in bolt fasteners.

Types of flat washers

Flat washers are also divided into many different types, such as: thickened flat washers, enlarged flat washers, small flat washers, nylon flat washers, non-standard flat washers, etc.

Spring washers

Spring washers are also called elastic washers. They are similar in appearance to flat washers, but with an additional opening, which is the source of their elasticity. The production process of spring washers is also stamping, and then a cut is required.
