Best-selling U Bolts

U-bolts are industrial fasteners with a curved body, shaped like the letter ‘U’ and have a thread at the end of each ‘leg’, which is used to secure the bolt with washers and nuts. These bolts are used to add stability and support.

Because of their unique shape, U-bolts are ideal for holding poles, beams, piping or tubes to walls or other surfaces. They come in a variety of sizes, materials and maximum loads and can be used for a multitude of purposes. When buying, it is important that you take into account the thread size, pipe size, inside leg length and between leg length.

With so many types available, it can be hard to know which U-bolt is right for you, which is why we’ve put together this guide, featuring some of our best-selling U-bolts.
