Steel structure bolt is a kind of high strength bolt, and also a kind of standard parts. Fastening performance is better, used for steel structure, engineering, so that the fastening effect. In general steel structure, steel structure bolts are required to be above grade 8.8, as well as grade 10.9 and grade 12.9, all of which are high strength steel structure bolts.
Steel structure bolt is divided into torsional shear type high-strength bolt and large hexagonal high-strength bolt, large hexagonal high-strength bolt belongs to the high strength level of ordinary screw, and torsional shear type high-strength bolt is the improvement of large hexagonal high-strength bolt, in order to better construction.
The construction of steel structure bolts must be first tightened and then tightened, and the steel structure bolts need to use impact type electric wrench or torque adjustable electric wrench; And the final tightening steel structure bolts have strict requirements, the final tightening torsion shear steel structure bolts must use torsional shear type electric wrench, the final tightening torque steel structure bolts must use torsional type electric wrench.
The large hexagon structural bolt consists of one bolt, one nut, and two washers.

Frequently Asked Questions (FAQ)
What is a steel structure bolt?
A steel structure bolt is a type of high-strength bolt and standard part designed to provide superior fastening performance in steel structures and engineering projects.
What are the common strength grades for steel structure bolts?
Steel structure bolts are generally required to be grade 8.8 or above. Common high-strength grades include 8.8S, 10.9S, and 12.9S.
What are the main types of steel structure bolts?
They are divided into large hexagonal high-strength bolts (which belong to the high-strength level of ordinary screws) and torsional shear type high-strength bolts (an improved version optimized for better construction).
How should steel structure bolts be tightened during installation?
They must be tightened in stages: first tightened using an impact type or torque adjustable electric wrench, followed by final tightening. Final tightening of torsional shear bolts requires a torsional shear electric wrench, while torque bolts require a torsional electric wrench.
What components make up a large hexagon structural bolt?
A large hexagon structural bolt consists of one bolt, one nut, and two washers.
What does a torsional shear steel structure bolt consist of?
A torsional shear steel structure bolt consists of one bolt, one nut, and one washer.
