Description:

Hex nut (Hexagon nut) used with bolt, screw, connecting the fastening parts.Also divide into stainless steel nuts and zinc plated carbon steel nuts. Among them the most widely type 1 hexagonal nut, class C nut is used for surface is rough, the accuracy is not high on machinery, equipment or structure;Class A and class B, nut is used for surface is bright and clean, high requirements for accuracy of the machinery, equipment or structure.Type 2 hexagonal nut thickness m thicker, more used to often occasions often require.The thickness of the thin hexagonal nut m thinner, more used to be the surface of the connection parts place restricted space.

Hexagon nuts according to the nominal thickness is divided into type I and type II and three thin.More than 8 nut is divided into two type type I and type II.
Type I of the most widely hexagonal nut, nut and type 1 points A, B, C level 3, which class A and class B, nut is suitable for the surface roughness is small, the high accuracy requirement of machinery, equipment and structures, and class C nut is used for surface is rough, the accuracy is not high on machinery, equipment or structure;Type 2 hexagonal nut thickness is thicker, more in occasions often require.
Nut is nut type 1 m nominal height of 0.8 D or regular hexagonal nut, the type size shall comply with the provisions of GB/T6170;
And the height of the 2 type nut than type 1 nut, the type size should comply with GB/T6175.2 type nut has two: the purpose of the one is by increasing the height of the nut to get a low without heat treatment, comparison of nut.
