Introduction to Twisted Shear Bolts
Twisted shear high-strength bolts are a special type of bolt with high strength and excellent torsional shear performance, widely used in engineering structures.
Twisted shear type high-strength bolts are mainly composed of screws, nuts, and bottom blocks. The screw is usually made of high-strength alloy steel, while the nut is made of a material that matches the screw. The bottom block is a key component of the torsional shear type high-strength bolt, and its design maximizes the torsional shear performance of the bolt. The bottom block is usually made of high-strength alloy steel, shaped like a torque frame, capable of withstanding large torques. When the screw is subjected to external force, the bottom block will convert the external force into torque and fix the screw in the bottom block through friction, thereby achieving the torsional shear connection of the bolt.
The characteristics of torsional shear high-strength bolts include:
High strength: Made of high-strength alloy steel, it has high strength and durability, and can maintain stable connections when subjected to large tensile forces and torques.
Twist shear performance: The design of the bottom block enables the twist shear type high-strength bolt to have good twist shear performance, which can convert external force into torque through the bottom block when subjected to external force, achieving the twist shear connection of the bolt.
Easy installation: The installation of torsion shear high-strength bolts is relatively simple. Simply thread the screw through the part and tighten the nut, without the need for additional processing or other special tools.
Twisted shear high-strength bolts are mainly used in the fields of building structures, vehicle manufacturing, and mechanical equipment, such as the manufacturing and maintenance of large bridges, high-rise buildings, automobiles, trains, and other transportation vehicles. When using torsion shear type high-strength bolts, it is necessary to pay attention to selecting the appropriate bolt grade and specifications, ensuring good matching between bolts and nuts, using appropriate tools and methods for tightening, and regularly checking the tightening status of bolts.
Application of torsional shear bolts
Twisted shear high-strength bolts are mainly used in industrial and civil buildings, highways and railways, bridges, tower frames, pipeline supports, lifting machinery, and other occasions that require friction type connections.
Twisted shear high-strength bolts are widely used in various fields, including construction, bridges, mechanical manufacturing, etc., due to their unique design and high strength. In the field of architecture, they are used to connect structures such as beams and columns, ensuring the stability and safety of buildings. In bridge construction, torsion shear high-strength bolts are used to construct large bridge structures such as suspension bridges, suspension bridges, and main bridges to ensure their stability and safety. In addition, they are also used in the field of mechanical manufacturing to produce various mechanical equipment, ensuring the efficiency and safety of the equipment.
The characteristics of twist shear high-strength bolts include an additional dodecahedron at the end, which requires the use of a specially designed electric wrench for installation. The unique design of this bolt provides higher strength and better reliability, making it an ideal choice in various engineering structures. Although the maximum diameter of twist shear high-strength bolts is only 24mm, their application range is wide, including but not limited to various occasions mentioned above, demonstrating their practicality and efficiency in small connections
