Products Description

A nut is a nut, a part that is screwed together with a bolt or screw for fastening. It is an original part that all production machinery must use. There are many kinds of nuts. Our common ones are national standard, British standard, American standard, and Japanese standard. Standard nuts. Nuts are divided into carbon steel, high-strength, stainless steel, plastic steel and other major types according to different materials. According to the product attributes, the standard numbers corresponding to different countries are divided into ordinary, non-standard, (old) national standards, new national standards, and American standards. , British system, German standard. The size is different, and the threads are divided into different specifications. Generally, the national standard and the German standard are represented by M (such as M8, M16), and the American and British systems are represented by fractions or # (such as 8#, 10#, 1/4, 3). /8) Fasteners, nuts are parts that tightly connect mechanical equipment. They can be connected together through inner threads, nuts and screws of the same specifications. For example, M4-0.7 nuts can only be matched with M4-0.7 screws ( In the nut, M4 means that the inner diameter of the nut is about 4mm, and 0.7 means that the distance between the two threads is 0.7mm); the same is true for American products, for example, a 1/4-20 nut can only be used with a 1/4-20 screw Matching (1/4 means that the inner diameter of the nut is about 0.25 inches, 20 means that there are 20 teeth in each inch).

Hex jam nuts are divided into three types: type I, type II and thin type according to their nominal thickness. Nuts above grade 8 are divided into two types: Type I and Type II.

Type I hex jam nuts are the most widely used. Type 1 nuts are divided into three levels: A, B, and C. Among them, A and B nuts are suitable for machines, equipment and structures with small surface roughness and high precision requirements. Grade C nuts are used on machines, equipment or structures with rough surfaces and low precision requirements;

The thickness of the II type hex jam nut is relatively thick, and it is mostly used in occasions that often need to be assembled and disassembled.

Type I nuts refer to ordinary hexagon nuts with a nominal nut height m≥0.8D, and their type and size should meet the requirements of GB/T6170;

The height of type II nut is higher than that of type 1, and its type and size should conform to GB/T6175. There are two purposes for adding type II nuts: one is to obtain a relatively inexpensive nut that does not require heat treatment by increasing the height of the nut.

Because the 8-level I-type nuts with D≤M16 do not need heat treatment, among the 8-level nuts, only the specifications of D>M16~39 can use the 2-type nuts.

Obviously, type I nuts that do not require heat treatment cannot meet the mechanical performance requirements of grade 9 nuts. Another purpose of specifying type II nuts is to obtain a grade 12 nut with better toughness. As the height of the nut increases, the guaranteed stress index can be achieved at a lower quenching and tempering hardness, so the toughness of the nut is increased.

Classified by tooth distance: standard teeth, regular teeth, fine teeth, very fine teeth and inverted teeth.

Classified by material: stainless steel hex jam nuts and carbon steel hex jam nuts, copper hex jam nuts, iron hex jam nuts, PC hex jam nuts

Classified by thickness: hex jam thick nuts and hex jam thin nuts.

According to the method of use: hot-melt copper nuts, hot-pressed copper nuts, embedded copper nuts and ultrasonic copper nuts

201 Stainless Steel Hex Jam Nuts Parameter

Applications:

The common six corners outside the world -- widely used, characterized by relatively large fastening force. The drawback is that there must be enough space for operation when installing. When installing, you can use live wrenches, open wrenches or glasses wrenches. The spanner needs large space for operation.
