    Confused flat root side fit 30pa spline

    I was wondering if any of you folks could check the tooth thickness and pin measurement values for this program i wrote. Here are the output results.
    Thanks in advance

    I am afraid I am too lazy to do that, but, why not go to a spline manufacturer's site and get the results for a given spline?

    Plug the basic parameters into your program and see what's what?

    p.s. I am assuming you mean "Slide fit"
