Product Description:

1.Key Specifications/Special Features:

1)Stainless Steel Hexagon nut. Material: 304, 316, 316L.etc.


2) International internal and external Stud with the mechanical property of Grade 4.8, 8.8, 10.9 and ANSI Grade 2, 5 and 8.


3) We commonly have GB, British standard, American standard, Japanese standard nuts. According to different materials, nuts are divided into carbon steel, high strength, stainless steel, plastic steel and other major types. According to the product attributes corresponding to different countries of the standard number is divided into ordinary, non-standard, (old) GB, new GB, American system, British system, German standard. Different sizes, threads are divided into different specifications.

 

General gb and German standards are represented by M (for example, M8 and M16)The lock nut is a kind of nut widely used in machinery and other industries. Its working principle is self-locking by the friction between the nut and the bolt. But the reliability of this self-locking is reduced under dynamic loads. In some important occasions we will take some anti-loosening measures to ensure the reliability of nut locking.

4) The nut of m4-0.7 can only be matched with the screw of m4-0.7 (in the nut, the inner diameter of the M4 finger nut is about 4mm, and the distance between the two thread teeth is 0.7mm). The same is true for American products, for example, a 1/4-20 nut can only be matched with a 1/4-20 screw (the 1/4 finger nut has an inner diameter of approximately 0.25 inch, and 20 fingers have 20 teeth per inch).

 

Hexagon nut according to the nominal thickness is divided into Type I, TYPE II and Thin Type. Nuts above grade 8 are divided into two types: Type 1 and type II.

 

Type I hexagon nut is the most widely used, type 1 nut is divided into A, B, C level 3, which A and B nut is suitable for the surface roughness is smaller, the precision of the machine, equipment and structure, and the C nut is used for the surface roughness, the precision of the machine, equipment or structure is not high; The thickness of type 2 hexagon nut is relatively thick, and it is often used in the occasion of assembly and disassembly.
