Product Description Product DescriptionA washer is a flat, ring-shaped component that is usually used in conjunction with fasteners such as bolts, screws, and nuts. In various mechanical connections and assemblies, it can not only enhance the stability of the connection but also protect the surfaces of the connected parts and extend their service life.Product Types1) Flat WashersThe most common type of washer, with a simple shape, is a flat, circular thin piece. It can increase the contact area between bolts or nuts and the connected surfaces, avoiding damage to the component surfaces caused by concentrated pressure. It is widely used in various general mechanical connection scenarios.2) Spring WashersThey are shaped like springs and have a certain degree of elasticity. After tightening the nut, the spring washer will use its own elasticity to generate a continuous reaction force to firmly press against the nut. Thus, even in the face of vibrations and impacts during the operation of the equipment, it can better prevent the nut from loosening. They are often used in occasions where high connection stability is required and there are certain dynamic loads.3) Rubber WashersMainly made of rubber materials, they have good elasticity and sealing properties. Besides playing a role in distributing pressure and preventing loosening, they are more commonly used in connection parts that require sealing, where they can effectively prevent the leakage of liquids or gases and ensure the sealing performance of the system.Material Selection of Products1. Carbon Steel WashersWith iron and carbon as the main components, they have a relatively low cost, moderate strength, and a relatively simple processing technology. 2. Stainless Steel WashersDue to containing alloy elements such as chromium and nickel, they have excellent corrosion resistance and can adapt to various harsh environments like humidity, acid-base, etc. Meanwhile, their strength and aesthetic appearance are also quite good.3. Copper WashersThey are relatively soft in texture and have good electrical conductivity, thermal conductivity, and corrosion resistance. Product ParametersWasher TypesSpecification Parameters Flat WashersInner Diameter: Determined according to the diameter of the matching bolt or screw, with various specifications from M2 to M50.Outer Diameter: The common size range is 5mm - 100mm, with different outer diameters corresponding to different specifications.Thickness: Ranging from 0.5mm to 5mm, which can be selected according to actual needs.Spring WashersThe inner and outer diameter specification ranges are similar to those of flat washers, and the thickness is usually between 1mm and 3mm. The elastic parameters of spring washers are designed and produced according to different standards and application requirements.Rubber WashersThe inner and outer diameters are customized according to the size of the matching parts, and the thickness is generally between 1mm and 10mm. The appropriate thickness can be selected according to the sealing and cushioning requirements. The physical properties such as hardness and tensile strength of rubber washers can also be adjusted according to different application scenarios. Application Fields of ProductsMachinery Manufacturing,Construction Engineering,Automotive Industry,Electronic and Electrical Appliances and so on.
