Product Introduction


U bolts available in a range of sizes and finishes to support different loads, torque requirements and environments.

A U-bolt is an industrial fastener in the shape of the letter U with two threaded arms (or legs) extending from a curved base. U bolts are typically used to support pipework or to attach a part to a pole, beam or wall, where the “u” shape keeps it firmly in place, adding 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.
