Product Description An In-Depth Look at Steel Structure High-Strength Torsion Shear BoltsThe Steel Structure High-Strength Torsion Shear Bolt is a specialized and advanced fastener, easily identified by its distinctive semi-circular head and the breakaway "plum" head (also commonly referred to as a splined end) at the bolt's tip. This design represents a significant improvement over traditional large hexagonal high-strength bolts, offering a more reliable and quantifiable method for achieving correct clamp force in critical structural connections.The installation process for these high-strength bolts is a precise, two-stage procedure that is crucial for ensuring joint integrity. For optimal and safe construction, the initial tightening must always be followed by a final tightening phase. The initial tightening, which brings the connected plates into firm contact, is typically performed using an impact wrench or, for greater precision, a torque-adjustable electric wrench. This first stage pre-tensions the bolt and secures the assembly.The unique advantage of the torsion shear bolt comes into play during the final tightening. This process is controlled by the splined plum head at the bolt's end. A special wrench grips this splined end, and using the principle of torque reaction, the bolt is tightened in the reverse direction. As the nut is turned, the tension in the bolt shank increases until the prescribed preload force is reached. At this exact point, the narrow section of the splined end shears off cleanly, providing a clear, visual, and irreversible confirmation that the bolt has been properly tensioned. This fail-safe mechanism eliminates guesswork and ensures consistent, reliable clamping force across all connections in a steel structure.As a leading Chinese factory specializing in torsion shear high-strength bolts for steel structures, we are your trusted partner for all your construction and manufacturing needs.
