All Electronics is selling these stainless steel thumbscrews with 8-32 thread. Thought maybe some might be interested in them for deck hold downs. https://www.allelectronics.com/item/sc-58/8-32-x-5/8-knurled-thumb-screw/1.html
Interesting idea. I personally prefer other options, but hey whatever gets the job done. I wonder how one of those would hold up to a direct hit.
