What is a U-bolt?

U-bolts are metal rods bent into the shape of the letter “U” with screw threads at each end. The threaded ends are designed to be fastened by securing nuts and washers; they can also be used with a crosspiece/seat spanning both threaded ends 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. They work by sitting around and clamping an object within the “U” shape and attaching to a surface with the help of the securing nuts.

U-bolts come in a variety of sizes, with different thread lengths and different grades. They are generally made of durable materials like plain carbon steel, mild steel (often plated with zinc for corrosion resistance), or corrosive resistance A2 / 304 or A4 / 316 stainless steel.

Use of U-bolt

U-bolts are typically used to support pipework, tubing, round objects 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.

They are also used as framing fasteners and anchors for foundations and roofs, conduit holders and bolts for motor and engine shaft components.

They may even be used to hang wrought iron pipe in mechanical installations or act as anchor bolts to be embedded in concrete.

They are also used for heavy equipment, conduit Support, as engine components, piping support as well as roof and foundation anchors.
