Choosing a U-bolt
Measure what the U-bolt is going around. For pipe, the nominal bore (NB) or the inside diameter of the U sets the size. For a section, measure the width. Then pick the thread: metric (M) or BSW, and the length for the thickness of the support plus the nuts. Round bend U-bolts suit pipe and round bar, and square bend U-bolts suit square or flat sections.
For the material, hot dip galvanised steel is the usual outdoor choice and zinc plated suits indoor use. For corrosive or wet conditions, the Inox World U-bolts are 316 and 304 stainless steel. Check the listing for what is supplied, for example nuts, washers or a kit.
Always check the data sheet. Confirm the thread, size, material and what is supplied before you order, especially for load bearing or structural applications.
