Spring washer is widely used in the bearing and non bearing structures of general mechanical products. It is characterized by low cost, convenient installation and suitable for parts with frequent assembly and disassembly. But the spring washer’s anti loose ability is very low! Especially in Europe and the United States, the adoption rate of high reliability products is very low, especially the important load-bearing structure connection has been abandoned for many years. In our country, there are some applications in military industry, but the stainless steel materials are improved. It is said that steel spring washer has been banned in CASC for a long time! It is also said to be very unsafe, there are two reasons: 1 is the “expansion circle”, 2 is hydrogen embrittlement.
