Chinese Standard ( GB / T41 - 2000 ) Galvanized Hex Nut Iron Galvanized
Hex nuts according to the nominal thickness is divided into I type, II and thin three. 8 or more nuts are divided into type I and type II two types.
Type I hex nuts are the most widely used. Type I nuts are divided into three grades A, B and C, of which A and B nuts are suitable for machines, equipment and structures that require less surface roughness and require higher precision C-level nuts are used for rough surfaces and low precision machines, equipment or structures. Type II hex nuts are thicker and are often used where disassembly and assembly are often required.
Type I nut refers to the nut nominal height m ≥ 0.8D ordinary hex nuts, the type size should be consistent with the provisions of GB / T 6170;The height of type II nut is higher than that of type I nut. The type and size should be in accordance with GB / T6175. The purpose of adding II nuts is twofold: First, get a nut that is not heat-treated and has a low cost by increasing the height of the nut.
Because D ≤ M16 8-level I-type nut without heat treatment, it is in the 8-level nuts, only D> M16 ~ 39 specifications with type II nut,
Obviously without the heat treatment of type 1 nut can not reach the mechanical properties of 9-level nut requirements. Specified Type II nut for another purpose to obtain better toughness 12-level nut. As the nut height increases, the lower the quenching and tempering hardness can be achieved to ensure that the stress indicator, it increases the nut toughness.
Classified according to the pitch: standard teeth, regular teeth, fine teeth, fine teeth and anti-tooth.
According to the material classification: stainless steel hexagonal nuts and carbon steel hexagonal nuts, copper hexagonal nuts, iron hexagonal nuts.
By thickness classification: hexagonal thick nut and hexagonal thin nut.
Classified according to the method of use: hot-melt copper nut, hot-pressed copper nut, embedded copper nut and ultrasonic copper nut.
