The Critical Role of High-Strength Bolts in Structural Safety

Keywords: High-Strength Bolts, BoltsIn bridges, high-rise buildings, and industrial machinery, joint failure is not an option. This is where high-strength bolts come in. These specialized bolts, such as ASTM A325 or A490 (or metric 10.9), are manufactured from alloy steels and undergo heat treatment to achieve superior tensile strength and clamp load. They are tightened to a specified preload (torque), creating connections that can withstand immense static and dynamic forces, forming the literal backbone of modern infrastructure.
