Stud bolt ASTM A320 L7 -16 "Thread to Thread" Class 2A c/w 2 Heavy Hex Nut ASTM A194 Gr.7L Class 2B

 

 

 

Hex Head Nut play the role of a component of all manufacturing machinery. It fastener other components. There are kinds of nut. We have common national standard, German standard, the British standard, American Standard, the subject of the nut. There are many kinds of lock nut. Hex Head Nut is very common.

Hex nut, according to the nominal thickness, is divided into type I, type II and thin nut. Hex Jam Nut. Above Grade 8 nuts , which is divided into Type 1 and Type II two types.

I type hexagon nuts widest application, a nut is divided into A, B, C three, where A and B grade nuts applied to the surface roughness is small, the high requirements for precision machinery, equipment and structures, and C grade nuts are used for relatively rough surface of the machinery, equipment or structures less precision; type 2 hex nut relatively thick, more often need to be used in assembly and disassembly of the occasion.

Type 1 nut refers nominal nut height m≥0.8D ordinary hex nut, of the type size should be consistent with the provisions of GB / T6170's;

The height of type 2 than type 1 nut to nut, of the type size should be consistent with GB / T6175. Increase in type 2 nuts two purposes: First, to obtain a nut without heat treatment by increasing the height, relatively low nut.
