U-bolts feature machine threading on both arms and are designed to be inserted into two pre-drilled holes. They are primarily used to anchor cylindrical objects such as pipe, conduit, cable, tubing, round bar or rope. In some applications, U-bolts may be inserted into wet concrete with the threaded arms pointing up. Once the concrete sets around the ''U'' shaped end, the U-bolt will be firmly anchored into place and the protruding threaded tips can be used to attach objects to the concrete.
