Application and classification of steel structure anchor bolts

Release date:2018-11-05 Author: Click:

Steel structure anchor bolts are high-strength bolts and are also a standard part. The fastening performance is better, and it is used for the steel structure and engineering to make the fastening effect. In general steel structure, the required steel structure anchor bolts are all above 8.8, and there are 10.9 and 12.9 grades, all of which are high-strength steel structure anchor bolts. Sometimes the bolts on the steel structure do not need plating. , use the true color is OK.


Steel structure anchor bolts are mainly used in steel structure engineering to connect the connection points of steel structural steel plates.


Steel structure anchor bolts are divided into torsional shear type high strength bolts and large hexagonal high strength bolts. Large hexagonal high strength bolts belong to the high strength grade of ordinary screws, while torsion shear type high strength bolts are improved of large hexagonal high strength bolts for better construction. .


The construction of steel structure anchor bolts must be tightened immediately after initial tightening. The initial tightening steel structural bolts need to use impact electric wrench or torque adjustable electric wrench; and the final tight steel structural bolt has strict requirements, and the final tight torsion shear steel structure Torsional-type electric wrenches must be used for bolts, and torque-type electric wrenches must be used for final tightening-type steel structural bolts.


Large hexagonal steel structural bolts consist of one bolt, one nut and two washers.


Twisted steel bolts consist of a bolt, a nut, and a washer.
