Nanjing high-strength bolt models are complete and shipped nationwide

   Bolts made of high-strength steel or that require a large preload can be called high-strength bolts. High-strength bolts are mostly used for the connection of bridges, rails, high-pressure and high-voltage equipment. The fracture of this bolt is mostly brittle. High-strength bolts used in high-pressure equipment require large prestressing in order to ensure the sealing of containers.
   High-strength bolt connection is to prevent them from slipping each other by the friction force between the contact surfaces of the connectors, and in order to make the contact surface have enough friction, the clamping force of the component must be improved and the friction coefficient of the contact surface of the component must be increased. The clamping force between the components is achieved by applying a pretension force to the bolts, so the bolts must be made of high-strength steel, which is also the reason for the so-called high-strength bolted connection.
   Applications of High Strength Bolts:
   1. High-strength bolts are high-strength bolts and belong to a standard part. High-strength bolts are mainly used in steel structure engineering to connect the connection points of steel structure steel plates.
   2. High-strength bolts are divided into torsional shear high-strength bolts and large hexagonal high-strength bolts, large hexagonal high-strength bolts belong to the high-strength level of ordinary screws, and torsional shear high-strength bolts are improved types of large hexagonal high-strength bolts, in order to improve the construction.
   3. The construction of high-strength bolts must be tightened first and then finally, and the initial tension of high-strength bolts needs to be used with impact electric wrenches or torque adjustable electric wrenches; The final tension high-strength bolt has strict requirements, the final tension torsion shear type high-strength bolt must use a torsion shear type electric wrench, and the final torque type high-strength bolt must use a torque type electric wrench.
   If you are looking for a high-strength and high-quality product, then high-strength bolts are the way to go. We believe that Nanjing Knetvo fastener products will be able to bring greater success to your project, and will also create more successful cases with integrity and quality. Let's work together to build a better future!
