Zinc Plated U-Bolts for 6” pipes work great for attaching parts to poles, signs, beams, or walls. This U-Bolt has a width of 6-3/4" and is designed to fit around 6" ID piping which has an OD of 6-3/4" but is versatile enough for many other projects. The 6” 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.
