At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 3570. Round-bend U-bolts for clamping pipes/tubes, supplied with two hex nuts. DIN 3570 covers Form A (round bend) sized by nominal pipe/tube outside diameter (approx. 20-500 mm), typically threaded M8, M10, M12, M16. Leg (shank) lengths vary by manufacturer for the required clamp reach, so the values below are representative of common stocked sizes.
