Product Description

Carbon Steel Hexagon Nut Black oxide Plating / M3 M8 M12 hex nut


The hexagonal nut is used in conjunction with screws, bolts and screws to connect and fasten parts. Among them, the Type 1 six-purpose nut is the most widely used, and the C-grade nut is used for machines, equipment or structures with relatively rough surfaces and low precision requirements; A-grade and B-grade nuts are used for relatively smooth surfaces and high precision requirements. machine, equipment or structure. The thickness M of the type 2 hexagon nut is thicker, and it is mostly used in occasions where assembly and disassembly are often required. The thickness M of the hexagonal thin nut is relatively thin, and it is mostly used in situations where the surface space of the connected parts is limited.

Generally we have to divide the fine tooth nuts and coarse tooth nuts, but in fact, no matter what fine tooth, coarse tooth, their specifications are the same, their specifications have M3, M4, M5, M6, M8, M10, etc.. But there is another kind, there are divided into the British system, the United States system of hexagonal nuts, which is also just a different national standards and themselves. Chinese production, called the national standard hexagon nuts.


There are generally two kinds, one is iron, that is, carbon steel. One is stainless steel, of course, there are copper, aluminum nuts, but these are less used. Copper is still more or less useful, like aluminum nuts are rarely used.
