A rule of thumb is that the right tap drill is around 85% for coarse threads and 90% for fine threads which feature a higher number of threads per axial distance. As a general practice, tapping torque should equal approximately 70% of the fasteners torsional strength. In production tapping we never use hand taps, because they trap chips and. 162 rows the tap size chart provides a list of standard size taps, specifying the diameter and thread spacing, for fractional, metric, and screw sizes.
