    The insert will be a steel insert vs just the re-tapped aluminum.

    So to use that insert I'd use the 9/16 tap and a 33/64 drill?

    On a slightly unrelated topic, my bolts had lock washers before, but they're in bad shape. Can I use a normal washer or do I need new lock washers?

    Right on!!! I haven't seen these before but they look to be a whole lot easier and certainly a lot cheaper.

    For sure, the $90 plus for the time sert kit was kind of a turn off

    Here is what we did once, put Teflon tape on the bolt threads, then get some A-B Epoxy or JB Weld fill the hole with it thread in the bolt let it dry and with the Teflon on it the bolt should come right out. Belzona works better buy is way spendy. worth a try.

    Thanks all for the help. Went with the Fastenal inserts and am officially leak free.
