U-bolt is an industrial fastener in the shape of the letter U with two threaded arms (or legs) extending from a curved base. A round u-bolt has smoother bends compared to a square bend one.

Uses of U-bolts are diverse which may include supporting pipework or attach a part to a pole, beam or wall. The “u” shape of U-bolt keeps it firmly in place, offering stability to the support.

The threaded ends are designed for use with washers and screws and can also be used with a crosspiece spanning both threaded arms of the bolt, to make it more secure in certain settings and uses. U-bolts are designed to be inserted through holes that have already been drilled or punched.

Often used as framing fasteners and anchors for foundations and roofs, pipe and conduit holders and bolts for motor and engine shaft components. Specifications of U-bolt includes material type, thread dimensions, inside diameter, and inside height.
