Anchor bolt, this bolt is used to fix the machine on the ground. Because 

it has strong stability, it is often seen in Bridges, mines, railways, highways,

 power enterprises, cement factories, automobiles, motorcycles, tower

 cranes, boiler steel structures, long-span steel structures and large buildings

Commonly used anchor bolt installation can be divided into embedment 

method and reserved hole method. Embedment method directly embedment

 anchor bolt when concrete is poured. The reserved hole method is to clean 

the holes after the equipment is in place, put the anchor bolts into the holes,

 and then fix the holes by grouting.

The commonly used materials of anchor bolts are Q235B, Q355B, 35#, 45#, 

40Cr, 35Crmo, and there are more scenes of Q235 material for anchor bolts, 

and there are grade requirements for the needs of greater tensile force and 

shear resistance. The main grades are 4.8, 6.8, 8.8, 10.9 and 12.9. The higher

 the grade, the higher the strength, generally 8.8 grade and above can be 

achieved by tempering heat treatment.

Scope of 

application

Carbon steel fasteners are widely used in industry, furniture decoration and other industries, making them unanimously welcomed by various industries.
