U-Bolts
U-Bolts are U-shaped fasteners with threaded ends, designed for clamping, securing, and supporting pipes, poles, conduits, and structural elements. These bolts provide high holding strength and stability, making them ideal for automotive, piping, marine, and heavy equipment applications.
At Rajal Industries, we manufacture precision-engineered U-bolts that conform to DIN, ASME, and general bolt standards, ensuring high tensile strength, corrosion resistance, and secure fitment across diverse industrial uses.
