TAP SIZES

Click on the tap size chart to the right for tap sizes and tap drill sizes for metric taps.

The tap drill sizes noted are only starting points. They will yield a theoretical 75% depth of thread, depending on many factors that include depth of hole, accuracy of your set-up, and material being drilled and tapped.

You will probably need to adjust these numbers to fit your application.
