Structural Bolts

Structural Bolts for High-Strength Steel-to-Steel Connections

Structural bolts are engineered fasteners designed for critical load-bearing applications where strength, precision, and reliability are non-negotiable. Commonly used in commercial construction, infrastructure projects, and heavy industrial assemblies, structural bolts are specifically manufactured to meet stringent standards for steel-to-steel connections in structural frameworks.

Designed for Structural Integrity and Safety

Structural bolts are produced to exact specifications that ensure consistent clamping force and predictable performance under extreme loads. These fasteners typically feature a heavy hex head and are used in conjunction with structural nuts and hardened washers to create a complete bolting system. When properly installed, structural bolts deliver uniform tension that resists vibration, shear forces, and fatigue over long service life.

Grades, Standards, and Materials

Most structural bolts are manufactured to recognized standards such as ASTM specifications and are commonly available in high-strength grades. These bolts are typically produced from heat-treated alloy steel, offering superior tensile and yield strength compared to standard hex head cap screws. Their controlled chemical composition and mechanical properties ensure compliance with building codes and engineering requirements for bridges, buildings, towers, and industrial structures.

Applications in Construction and Industry

Structural bolts are widely used in steel framing, beam-to-column connections, bridges, highway structures, and heavy equipment foundations. Their reliability makes them essential for projects where safety, load capacity, and long-term performance are critical. Many structural bolts are installed using calibrated torque or tensioning methods to achieve precise preload, ensuring consistent joint performance.
