Hex nuts are used in conjunction with bolts and screws to connect and fasten the mechanical parts. Type 1 Hexagon nuts are most widely used for rough surfaces. A machine, device, or structure that does not require high precision; Class A and B nuts are used in machinery, equipment or structure whose surfaces are smooth and clean, and the thickness m of type .2 hexagonal nuts is thicker. Hexagon thin nut has a thin thickness m and is mostly used in cases where the surface space of the connecting parts is limited.

Common color, blackening, galvanizing are ordinary carbon steel nuts.Nuts generally have a performance rating

GB nuts for machinery, construction, electrical industry as a fastening role, one end is hexagon head for wrench fastening, the other end is Thread, according to the use of different thread length is also different, full thread and half thread.

GB nuts are generally divided into two kinds: GB30 nuts, GB21 nuts, the difference is that the GB30 hexagon head is larger than the GB21. The materials are Q235. The grade is 4.8, and the hardness is weak. It is used for low hardness and infrequent activity The area that people call a plain nut. Typical application: fixing and fastening for machinery and construction industry.

Nuts are nuts, and bolts or screws screwed together to play a role in fastening parts, all manufacturing machinery must use a component according to the different materials, divided into carbon steel, stainless steel, non-ferrous metals (such as copper) and other major types.
