Anchor Bolts are critical components in structural engineering, designed to transfer loads from superstructures to concrete foundations. Their robust design—featuring a threaded end for nut engagement and a non-threaded anchored end (J-shaped, L-shaped, or with a forged head)—ensures secure embedment and resistance to pulling or shear forces. Widely used in commercial construction, industrial machinery mounting, and infrastructure projects, these bolts are engineered for durability, corrosion resistance, and compliance with global building codes.
