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 U-bolt is often used in lumber applications. Zinc plating helps reduce corrosion in normal atmospheric conditions.
Stainless steel U-bolts are ideal for marine and outdoor use due to their resistance to atmospheric corrosion. They are passivated for enhanced corrosion resistance and are non-magnetic. These U-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, semi-round, and square. The diameter options are M6, M8, M10, and M12. Surface treatments include zinc plating and hot-dip galvanizing, which further enhance corrosion resistance.
U-bolts are primarily used to support pipework, where they secure pipes carrying fluids or gases. In engineering terms, U-bolts are often described based on the size of the pipe they are intended to support.
