This is a pretty much our standard U-bolt but with the Rockwell Square Tubed twist (3 5/8" square tube), they have .625" (5/8) Rolled Threads for extra strength and the threading is 5" long so they will fit! Cut off what you don't need after they are on, and they are also Grade 8. If they fit use them (if they don't fit drill your plates until they do)! All of our U-bolt plates are recomended to use 5/8" U bolts. Comes with Tallnuts and Hardened Ubolt Washers. U-Bolts are Sold individually.
