Zinc Plated U-Bolts for 1/2” pipes work great for attaching parts to poles, signs, beams, or walls. This U-Bolt has a width of 15/16" and is designed to fit around 1/2" ID piping which has an OD of 15/16" but is versatile enough for many other projects. The 1/2” U-Bolts support heavy objects and often times work better than routing clamps depending on the application. Our high quality round u-bolts are domestic products that are proudly made here in the USA. Zinc U-Shaped Bolts Hook around piping or cables and should be used with the correct size Zinc Hex Nuts and Zinc Washers.
