    drill sizes for taps
    « on: December 08, 2002 - 07:36:09 PM »
    we all have broken bolts or trying to adapt new to work so they are safe to drive so  here is the charts

    remember that

     5/16 + 3/16= 8/16 which  is 1/2 the wrench size
    3/8 + 3/16= 9/16 the wrench size

    Usually the 75% theory works. Use a drill as close to 75% of the thread diameter. Not sure about self tapping screws. There are always exceptions, but this has worked for me.
