Flat washers are used in our daily life to reduce friction, prevent leaks, isolate, prevent loosening or distribute pressure. They are found in many materials and structures, and are used to perform a variety of similar functions. Limited by the material and process of threaded fasteners, the bearing surface of bolts and other fasteners is not large, so in order to reduce the compressive stress on the bearing surface and protect the surface of the connected parts, flat washers are used. I believe that the majority of male compatriots have played with pistols when they were young, and have also disassembled the parts inside the mobile phone. Especially in the case of a jammed pistol, we have to do it manually. Flat washers are used at the end of the pipe to reduce friction, prevent leakage, isolate, prevent loosening, or distribute pressure.
The size of flat washers and their wide range of uses also result in different specifications of flat washers, no matter their material or their shape will not change differently, and flat washers are usually thin pieces of various shapes , used to reduce friction, prevent leaks, isolate, prevent loosening or distribute pressure. They are found in many materials and structures, and are used to perform a variety of similar functions. Limited by the material and process of threaded fasteners, the bearing surface of bolts and other fasteners is not large, so in order to reduce the compressive stress on the bearing surface and protect the surface of the connected parts, 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-shaped, wave-shaped and conical elastic washers are used. What is the general specification of the flat washer, and are there many specifications of the flat washer? Wait for the specifications of some washers.
