Flat washer standards, there are some standards you don’t know [hardware]

The flat washer standard has the GB standard of ABC and the grade of hardness. Then, in addition to the GB standard, Xiaoshuo will take you to know more about the industry: 　1. If it is a flat washer for bolt connection, it does not need high hardness. If the hardness is high, the uneven contact surface will be crushed, and there is no relative Movement and friction do not require high hardness. Just use the original hardness of the material, and make the contact surface softer to increase the effect better.　2. Flat washers are usually thin pieces of various shapes, used to reduce friction, prevent leakage, isolate, prevent loosening or distribute 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. Therefore, in order to reduce the compressive stress of the pressure-bearing surface to protect the surface of the connected part, washers are used.　3. Flat washers without mechanical performance requirements are generally made of corner materials, such as Q235A. If there is a hardness requirement but not high, it can be rolled with a thicker plate to achieve the required hardness. Hardware, 15 years of ingenuity and focus on flat gasket standards, with 20000+ sets of mold customization and production, monthly 100+ sets of mold processing capacity, 5000 square meters production workshop, 3 million punching next-day production capacity, stamping accuracy up to 0.01mm, 16 quality Strictly check every layer of inspection. It can quickly solve the time-critical problem for you, solve the problem of the accuracy of your gasket, and solve the problem of the quality of your bulk products. Choose, choose to rest assured!
