Pretty solid hardware. I used a good marine grade adhesive / sealant, e.g. Loctite PL or 3M 3000, 4000, 5200. I used it over the area of contact and not just the holes. (I used loctite cuz menards had it.)The biggest PITA ("pain") is that you have some pretty long, pretty sturdy SS bolts protruding through the transom, that i had to cut off and grind down as my boat is an inflatable and the protrusions looked like a puncture risk. If you don't mind the long bolts sticking through, then it's not a problem. Remember you are drilling through your transom so take time to measure, mark and drill ONE TIME.Product works great after install.
