Hex Nuts

Jinrun is a Hex Nuts factory, the main specifications from M5-M24, IFI 1/4 to 1 inch, cheap, reliable quality.The nut, which is screwed together with the bolt or screw to play a fastening role. Through the inner thread, the same size nut and bolt can be joined together, and the nut is a component that must be used in all manufacturing machinery.

There are many kinds of nuts, according to the different materials, divided into carbon steel, high strength, stainless steel, plastic steel and other types. According to the product attributes corresponding to different national standard nuts are divided into ordinary, non-standard, (old) national standard, new national standard, American system, British system, DIN standard, etc. We commonly used carbon steel nuts have 4, 5, 6, 8, 9, 10, 12 and other seven performance grades. Hex Nuts are divided into three types according to nominal thickness: type I, type II and thin type. Nuts above grade 8 are divided into two types: Type I and type II. Type I hexagon nuts are the most widely used, and type I nuts are divided into A, B, and C three levels, of which class A and B nuts are suitable for machines, equipment and structures with small surface roughness and high precision requirements; The C-class nut is used for machines, equipment or structures with rough surfaces and low precision requirements; The thickness of type II hexagon nuts is relatively thick, and it is used in occasions where installation and disassembly are often required.
Under normal circumstances, the strength of the bolt selected during design will be one level higher than that of the corresponding nut, which can ensure that the life of the screw is longer than that of the nut when used together. This in the sample disassembly and replacement of fasteners, the cost of replacing the nut will be cheaper and more convenient.
