The unthreaded portion is of specific grip length, plated or unplated, and is machined to a tolerance of one thousandth (0.001) of an inch (0.025 mm) or less of a specific diameter for items one inch (25 mm) or less in diameter. 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.
