Pin Type Anchor Bolts are heavy-duty fasteners designed for anchoring structural components, machinery, and industrial equipment into concrete foundations. These bolts provide secure embedment and high pull-out resistance, ensuring long-term stability in seismic, high-vibration, and heavy-load applications.
At Rajal Industries, we manufacture precision-engineered pin type anchor bolts that conform to ASTM and IS standards, ensuring exceptional tensile strength, corrosion resistance, and durability. Our pin type anchor bolts are widely used in construction, bridges, power plants, and industrial installations.
