A SCREW, MACHINE or SCREW, CAP, SOCKET HEAD whose unthreaded portion is of specified grip length, plated or unplated, and is machined to a tolerance of one thousandth ( . 1 IN.) ( . 25 mm) or less of a specific diameter for items (1. IN.) (25 mm) or less in diameter. Items over (1. IN.) (25 mm) in diameter shall have a tolerance of fifteen ten thousandths ( . 15 IN.) ( . 38 mm) or less. The nominal major diameter of the threads shall be at least one thousandth ( . 1 IN.) ( . 25 mm) below the minimum shank diameter, but not below the minimum major diameter for applicable class of fit, as shown in the Screw Thread Standards, FED STD H28 and/or other nationally recognized standards.
