A U-bolt is a bolt shaped like the letter "U" with two threaded ends extending from a curved base. It is commonly used for attaching pipes to machines or structures. A square-shaped U-bolt is often used in lumber applications. Zinc plating helps slow down corrosion in normal atmospheric conditions. Stainless steel U-bolts are ideal for marine and outdoor applications due to their resistance to atmospheric corrosion. They are passivated for enhanced corrosion resistance and are non-magnetic. These bolts are typically sold in bulk and come with two hex nuts for assembly. They are manufactured from steel with a stainless steel finish.
Available bend types include round bend, semi-round bend, and square bend. The diameters available are M6, M8, M10, and M12. Surface treatments include zinc plating, which retards corrosion, and hot-dip galvanization for added durability. U-bolts are primarily used to support pipework, where they hold pipes carrying fluids or gases. In engineering terminology, a U-bolt is often described based on the size of the pipe it is intended to support.
