press-fit nut is a precision fastener used for connecting sheet metal parts. One end has a non-slip toothed flange, and the other end is a smooth cylinder with a metric machine thread. Common sizes range from M2 to M10. It offers excellent connection performance, firmly fixing to sheet metal parts and other workpieces via press-fitting. It is widely used in electronic equipment housing fixing, automotive parts assembly, furniture panel installation, and automated equipment frame assembly. Common materials include high-quality low-carbon steel, medium-carbon steel, alloy steel, 304 stainless steel, 316 stainless steel, brass, and aluminum alloy. In terms of strength grades, carbon steel is available in 4.8, 6.8, and 8.8 grades, stainless steel in A2-50, A2-70, A4-70, and A4-80 grades, and non-ferrous metals are at least 4.8 grade. Various surface treatments are available, including environmentally friendly blue-white zinc plating, color zinc plating, black zinc plating, environmentally friendly nickel plating, zinc-nickel alloy plating, Dacromet coating, electrophoresis, PVD, stainless steel natural finish, and stainless steel passivation, meeting the needs of different environments.
