Large hexagon bolts for steel structure Large hexagon bolts for steel structure
Our steel structure bolts are available in high-strength grades including Grade 8.8S, 10.9S, and 12.9S, which are ideal for demanding engineering applications.
They are divided into torsional shear type high-strength bolts and large hexagonal high-strength bolts. Torsional shear types are an improvement over large hexagonal bolts for better construction efficiency.
A large hexagon structural bolt set consists of one bolt, one nut, and two washers.
A torsional shear steel structure bolt set consists of one bolt, one nut, and one washer.
Initial tightening requires an impact type electric wrench or a torque-adjustable electric wrench. For final tightening, torsional shear type bolts require a torsional shear electric wrench, while large hexagon bolts require a torsional type electric wrench.
