True to its name, U-Bolts are bolts in the shape of the letter U with screw threads on both ends. These handy bolts fit around and support pipe, conduit and tubing and are also used to lock down machinery or serve as an anchor for foundations and roofs. Unlike standard u-bolts, square u-bolts are ideal for holding strut channels, square tubing or flat items. Coming in a variety of inside width and thread sizes, u-bolts are used by construction workers, plumbers, electricians and mechanics to clamp tubing/round bar.
