    For that length of thread, you will need a tap with back clearance
    to allow for the extended cut in length, given that the shank is
    usually of a larger Diameter in a good set of taps. Also look at
    forming taps, these do not cut, but rather form a thread which will
    equate in a stronger thread especially in soft metals. For example a
    6-32 tap will require a hole size of .1065, but with a forming tap,
    this hole will be 1/8 or .125. Less stress on the tool and the user. 

    If you need assistance in getting the right size, give me a call. 

Best Regards.
