QdG[eo.aTiKM_hKEYdK L The system the callout uses is very important since similar screws can be different sizes. The thread size, pitch, and class as well as the type of tap the machinist is going to use determines the proper drill size. 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.".

A parting line is the location where separate parts of a mold or die come together. Metal 3D printing has rapidly emerged as a key technology in modern design and manufacturing, so its critical educational institutions include it in their curricula to avoid leaving students at a disadvantage as they enter the workforce. . Is this valid? . Perpendicularity is a fairly common symbol that requires the referenced surface or line to be perpendicular or 90 from a datum surface or line Runout is how much one given reference feature or features vary with respect to another datum when the part is rotated 360 around the datum axis. "I am a freshman and I needed to know this information for a engineering presentation and this was the easiest, "Never heard of using a rubber band to undo a damaged screw head. Per the standard, the pitch cylinder diameter must be used to evaluate the hole location and orientation, using centerline hole location plugs.
