Steel structure large hexagonal bolt is a commonly used high-strength bolt in steel structure connections, with a standard hexagonal head, usually used in conjunction with a nut and washer. The design of this bolt allows for the use of conventional wrench tools during installation to precisely apply the required torque, thereby achieving the expected preload force. The fastening performance of steel structure large hexagonal bolts is good, mainly used to connect and fix steel structural components, ensuring the stability and safety of the structure.
The standard for large hexagonal bolts in steel structures is GB/T1228. Each set includes one high-strength large hexagonal bolt GB/T 1228, one high-strength nut GB/T1229 for steel structures, and two high-strength washers GB/T1230 for steel structures, and should be manufactured in the same batch. This type of bolt is generally grade 10.9, but there are also 8.8 grades, but they are rarely used. The construction of large hexagonal bolts for steel structures must be initially tightened and then finally tightened. The initial tightening requires an impact type electric wrench or a torque adjustable electric wrench; And there are strict requirements for the final tightening, which require the use of specialized torque type electric wrenches or torque type electric wrenches.
Compared with torsion shear high-strength bolts, large hexagonal bolts require higher operating space, but in some open working environments, they provide greater flexibility, especially when adjusting torque to meet specific design requirements. Understanding the unique advantages and applicable scenarios of these two types of bolts can help make more reasonable design and construction decisions in steel structure engineering, ensuring that the connection of steel structures is both firm and efficient
Steel structure large hexagonal bolts are mainly used for connecting and fixing steel structures.
Steel structure large hexagonal bolts, as a high-strength bolt, are a type of standard component with good fastening performance. They are mainly used in steel structure engineering, especially when connecting steel plates. The design of this bolt allows for the use of conventional wrench tools during installation to precisely apply the required torque, ensuring the firmness and stability of the steel structure connection. In addition, large hexagonal high-strength bolts and torsional shear type high-strength bolts are indispensable components in modern steel structure engineering, each with its own characteristics and demonstrating their superiority in different application scenarios. Although high-strength bolts with large hexagonal heads require higher operating space, they provide greater flexibility in some open working environments, especially when adjusting torque to meet specific design requirements. The strength grade of this type of bolt is usually above 8.8, including 10.9 and 12.9, all of which are high-strength steel structural bolts.
