Hot dip galvanized U-Bolts for 8” pipes provide good corrosion resistance in most environments and work great for attaching parts to poles, signs, beams, or walls. This U-Bolt has a width of 8-3/4" and is designed to fit around 8" ID piping which has an OD of 8-3/4" but is versatile enough for many other projects. The 8” U Bolt pipe hanger supports HVAC, plumbing, and other heavy piping securely. Hot dip galvanized 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. U Shaped Bolts hook around piping or cables and should be used with the correct hot dip galvanized hex nuts and hot dip galvanized washers.
