Question #6905   Submitted by Answiki on 10/14/2022 at 07:38:09 AM UTC

What diameter should I pre-drill for an M7 tap?

The pre-drilled diameter of an M7 x 1.0 thread is 6 mm.


The pre-drilled diameter for tapping is given by the drilling diameter minus the pitch. For a standard M7 x 1.0 tap, you need to drill to 7 - 1.0 = 6 mm.
