High-strength bolts are mainly used in steel structure projects to connect the connection points of steel plates. High-strength bolts can be divided into: large hexagonal head high-strength bolts and torsion shear high-strength bolts according to the construction process, the connection performance and its own mechanical properties are the same, and both are the size of the torque to determine the size of the axial force of the bolt, but they still have differences, the following I take you to understand the difference between large hexagonal head high-strength bolts and torsion shear high-strength bolts.
A, the difference in appearance.
Large hexagonal head high-strength bolts and torsion shear high-strength bolts are different in appearance. The head of large hexagonal head high-strength bolts is hexagonal, while the head of torsion shear high-strength bolts is semi-circular, and its tail comes with a plum head.
B. The difference in installation.
Large hexagonal head high-strength bolts are installed with a torque wrench. The torsion shear high strength bolt is controlled by the plummer head at the end of the installation process, and the torque is used to reverse the bolt until the straight tooth-like end of the bolt is broken.
C. Differences in matching.
Large hexagonal head high-strength bolts and torsional shear high-strength bolt packages are not the same. Large hexagonal head high strength bolts are composed of a bolt, a nut and two flat pads. And torsion shear high strength bolts are composed of a bolt, a nut and a flat pad.
D. The difference in torque.
The torque of the large hexagonal high-strength bolts is controlled by the construction tools, while the construction of torsion shear high-strength bolts to use a special electric wrench, which belongs to the self-scaling type bolts, whose construction tightening torque is determined by the diameter of the cutout between the screw and the plummer head at the end of the bolt, that is, by its torsional breaking torque to control.
In general, large hexagonal high-strength bolts belong to the high-strength grade of ordinary screws, while torsion shear high-strength bolts are the improved type of large hexagonal high-strength bolts, although they are the same kind of bolts, but there are still great differences in some subtle aspects. Compared with the two, torsion shear high strength bolts have the advantages of easy construction, intuitive inspection, good force, quality assurance, etc. Most of the high-rise steel structure projects use this form.
Large hexagonal head high strength bolts and torsion shear high strength bolts are one of the main products of Nanning Aozhan hardware fastener manufacturers, complete specifications, spot supply, the product is recognized by the market, many corporate customers repurchase rate is very high, also very much looking forward to working with you, can send e-mail: info@aozhanfasteners.com, fast access to preferential bolt quotation.
