8.8 High Tensile Bolts
Name: High-strength bolts
Description: High-strength bolts are divided into torsion shear type high-strength bolts and large hexagonal high-strength bolts according to the construction process.
The torsion shear type high-strength bolt is composed of a bolt, a nut, and a washer. It is an improved type of large hexagonal high-strength bolts for the convenience of construction design.
High-strength bolts are mainly used in steel structure engineering. A very important feature of high-strength bolts is that they are limited to single use. They are generally used for permanent connections. Repeated use is strictly prohibited!
