The strength of the D ring or breaking strength is 10,000lbs. Rigging gear uses a 5 to 1 factor for working load capacities, in this case 2,000lbs. working load. Using the allen instead of the original screw supplied with the D ring "Shackle" weakens it. You may have noticed the over sized hole of the unthreaded part of the shackle and how lose it is at the cap side. But good news, the D ring isnt your weak link. If you use that tie down to pull in any other direction than a straight pull, you will snap that bolt that screws into the vehicle.
