    And this boys and girls is how new bolts are made.

    This is false.
    Metric vs SAE threads: as long as diameter and pitch are similar between the two frequently you can get a "false start". An example is 1/2 x 28 and 12 x 1.5. They look very similar from outward appearances.
    But when you try to mate them the threads are "out of time" with each other. Get 3-4 turns and the timing difference stacks up and the thread stalls out.

    Rays method of checking threads is the way to go without a pitch gage as long as you know what your "gage" thread is.



    Silly cstone, don't you know those are both male threads?

    Yeah, my method is just a quick and dirty way if you have an existing bolt you know fits and want to make sure the replacement bolt is the right pitch. I'm pretty good at distinguishing a 13 tpi bolt from a 28 tpi just by looking. Lol. Sometimes the 7 and 8 look pretty similar without lining them up. Same with the 11 and the 13.

    Yep. I've never seen a cross threaded bolt back off.
