High-Strength Structural Bolts

High-Strength Structural Bolts are core fasteners in modern steel structures, bridges, towers, and large equipment foundations. Their primary function in friction-type connections is to generate sufficient friction between layers through high preload to transfer loads. A complete set of High-Strength Structural Bolts typically consists of a bolt, a nut, and two washers (or one washer, depending on the standard). The connection pair must be supplied as a whole to ensure a stable torque coefficient. In high-rise building beam-column joints, stadium trusses, railway bridges, and wind turbine towers, High-Strength Structural Bolts have largely replaced field welding and ordinary bolt connections. Using High-Strength Structural Bolts not only improves installation speed but also gives the structure better ductility and ease of disassembly and maintenance.

Produkto funkcijos ir taikymas

Precise Preload Control System: Large Hexagonal Type: Stable torque coefficient; with a torque wrench, preload deviation can be ≤±10%.

Torque-shear type: Automatically achieves the designed preload through the torque-angle characteristics at the moment of breakage of the bolt head, unaffected by human torque errors.

Standard connection pair design: The hardness of the under-bolt washer and under-nut washer is matched to prevent indentation or wear during tightening. The chamfer direction of the washers is clearly marked to prevent reverse installation.

Strict batch management and traceability: Each batch of High-Strength Structural Bolts undergoes torque coefficient, wedge load, proof load, impact, and hardness testing. Product identification includes performance grade, specifications, standard number, and manufacturer code, ensuring traceability of project quality.
