Products Description

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.

Screw in the nut safety nut, thin rod screw connection nut, self-locking hexagonal cap nut, special anchor nut, hexagonal crown thin nut, and ring nut.

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.
