All-metal locking nuts follow the DIN980 standard, which is a standard for all-metal locking nuts, including two types: DIN980V and DIN980M.
"A2" and "A4" in A2-70 and A4-80 represent the types of stainless steel, where A2 usually refers to chromium stainless steel, while A4 refers to austenitic stainless steel. Specifically for A4-80, 80 means that its tensile strength is at least 800N/mm², which is a high-strength bolt type among stainless steel. Stainless steel bolts and nuts of this material are often used in applications that require high strength and corrosion resistance.
