WebA tap drill chart is a machinist’s must-have reference document that contains drill bit sizes, tap sizes, and their equivalent thread specifications that guide an engineer in fabricating threads and drill holes. Tap drill charts employ different measurement systems, including metric, wire gauge number, fractional, and letter. WebFor example, if you come across a box of machine screws with this label: M10 x 1.5 x 75. The first number after the letter M indicates the screw’s diameter. The second number is the screw pitch. The final number is the screw length. Remember, the measurements here are expressed in millimeters.
