Just a friendly tip: The larger and wider washer will be better serving if placed between the nut and lock-washer rather than simply resting under the bolt head (unless you're using a major league impact-driver to tighten the nut LOL). It spreads the load on the underside, where any pull-through issues will be far greater. I made utility plates almost identical to the ones with chain hooks and D-rings 20 years ago (and use them for hundreds of jobs), and when the bucket is high, with heavy items being lifted, pulled on, or suspended, the tension is on the hooks, thus spread to the washer(s) and nut on the underside. Another option would be to include a matching 1/4" plate on the underside, thus spreading the load/footprint, and increasing the strength of the unit. You have a great looking line of products. Good luck with your endeavor.
