The inner spherical flat washer, what is the role of the flat washer in daily life + solid as a rock

Inner spherical flat washers, flat washers are usually thin pieces of various shapes, used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. The following Xiaoshuo and you analyze the role of flat washers in life: Many materials and structures have such parts, which are used to perform various similar functions. Limited by the material and process of the 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 and protect the connected surface, washers are used. In order to prevent the loosening of the connection pair, anti-loose spring washers, multi-tooth lock washers, round nut stop washers, and saddle, wave, and cone elastic washers are used. Hardware, 15 years of focus on inner spherical flat washers, 5000 square meters production workshop, hundreds of precision processing and production equipment, more than 20 Ru0026D and design engineers, metal flat washers with an accuracy of 0.01mm, 3 million punching next-day production capacity, 16 quality The inspection starts from the raw materials and strictly controls each layer. Can quickly solve the problems of time, accuracy and quality for you!
