WebThe tapped hole callout format is: tap drill diameter + depth; thread specification + depth; quantity of holes desired (not included if only one hole is specified) Notice that when working with blind threads (i.e. Join your peers on the Internet's largest technical engineering professional community.It's easy to join and it's free. This symbol is not used as a replacement for datums and datum references. A datum feature is usually an important functional feature that needs to be controlled during measurement as well. However, this procedure engages the thread minor diameter, not the pitch cylinder, and it is only permitted when the note MINOR DIA is added below the feature control frame. The major diameter is the largest diameter of the cutout required for an internal thread, while the minor diameter is the clear opening for an internal thread. The callout basically corresponds to the length and diameter of the screws shaft.

Jbeckhou -- I don't know if it's been mentioned above as to what standard your drawings are using (and there should indeed be a note imposing a standard) but the ASME standard Y14.5 clearly states in paragraph 1.4(e) that "the drawing should define a part without specifying manufacturing methods.". Note that the tolerance class is also divided into A and B. Due to the specialized gauges required to locate threads from the pitch cylinder, it is good practice for engineers and designers to use the MINOR DIA note for internal threads and the MAJOR DIA note for external threads where possible.
