Items over one inch (25 mm) in diameter shall have a tolerance of fifteen ten-thousandths (0.0015) of an inch (0.038 mm) or less. The major diameter of the threads shall be at least one thousandth (0.001) of an inch (0.025 mm) below the shank diameter, but not below the major diameter for applicable class of fit, as shown in the screw thread standards, federal standard h28 and/or other nationally recognized standards. The head is not designed to be held or driven with an inserted driver, nor is it designed for rotation by the thumb and fingers. A locking feature may be incorporated in the design of the head or threads.
