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.
Construction & Tightening Requirements
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)
1. What grades are available for these steel structure bolts?
They are high-strength structural fasteners available in grades 8.8S, 10.9S, and 12.9S.
2. What is the difference between large hexagonal and torsional shear high-strength bolts?
Large hexagonal bolts function as high-strength versions of standard screws. Torsional shear bolts are an improved design developed to facilitate better and more efficient construction practices.
3. What components are included in a large hexagon structural bolt set?
A large hexagon structural bolt set consists of one bolt, one nut, and two washers.
4. What components are included in a torsional shear steel structure bolt set?
A torsional shear steel structure bolt set is composed of one bolt, one nut, and one washer.
5. What tools are required for tightening these steel structure bolts?
Initial tightening requires an impact type or torque adjustable electric wrench. For the final tightening, torsional shear bolts require a torsional shear type electric wrench, while torque bolts require a torsional type electric wrench.
6. What materials and sizes are available for these heavy hex bolts?
These bolts are made of carbon steel, with sizes ranging from M12 to M24, and are finished in black.
