Characteristics Of Spring Washers

Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost, easy installation, and suitable for parts with frequent assembly and disassembly. The washers are included in the quick and easy automatic selection, but the anti-loosening ability of spring washers is very low! Especially in products requiring high reliability in Europe and the United States, the adoption rate is extremely low, especially the important load-bearing structure connection parts have long been abandoned. Our country still has some applications in the military industry, but it has been improved to stainless steel materials. Steel spring washers have long been banned in CASC! It is also said to be very unsafe. There are two reasons: 1 is "expansion ring" 2 is hydrogen embrittlement.
Spring washers are often called spring washers in the screw industry. Its materials are stainless steel and carbon steel, and carbon steel is iron. The commonly used spring washers are M3, M4, M5, M6, M8, M10. M12, M14, M16. These specifications are more commonly used. The national standard for spring washers is GB/T 94.1-87, which specifies standard spring washers with specifications ranging from 2 to 48 mm. The reference standard is GB94.4-85 "Technical conditions for elastic washers - spring washers"
