**304SS / 316SS Stainless Steel Square U-Bolts** A U-bolt is a fastener shaped like the letter "U" with threads on both ends. It is commonly used to support pipes, tubing, and other cylindrical structures. Traditionally, U-bolts were described by the nominal bore size of the pipe they supported, which could be confusing as this number doesn’t directly correlate with the actual dimensions of the bolt. Today, U-bolts are used in a wide range of industries for clamping various types of tubes or round bars. As a result, a more practical measurement system is now applied, such as metric sizes (M2-M120), making them easier to use across different applications. --- ### Product Description
