Flat washer standard, the knowledge about standard parts and customized parts [hardware]

The flat washer standard is divided into with chamfer and without chamfer. A friend once asked if it was a standard part. Flat washers are divided into standard parts and customized parts. Xiaoshuo will share with you the use and standard numbering of the flat ring: Flat washers are usually thin parts of various shapes to reduce friction, prevent leakage, isolate, and prevent Loosen or disperse the pressure. Many materials and structures have such components, which are used to perform various similar functions. Limited by the material and process of threaded fasteners, the supporting surface of bolts and other fasteners is not large, so in order to reduce the compressive stress of the pressure-bearing surface to protect the surface of the connected part, washers are used. There are 9 standards for flat washers in my country. From 2000 to 2002, GB/T97.3-2000, GB/T5286-2001, GB/T95-2002, GB/T96.1-2002, GB/T96.2 were approved and issued respectively. －2002, GB/T97.1-2002, GB/T97.2-2002, GB/T97.4-2002 and GB/T5287-2002 and other flat washer standards.
