ITEM NAME   SCREW,CLOSE TOLERAN
DEFINITION  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 (0.001 IN.) (0.025 mm) or less of a
             specific diameter for items (1.000 IN.) (25 mm) or less in diameter.
             Items over (1.000 IN.) (25 mm) in diameter shall have a tolerance of
             fifteen ten thousandths (0.0015 IN.) (0.038 mm) or less. The nominal
             major diameter of the threads shall be at least one thousandth (0.001
             IN.) (0.025 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. The head is designed to be held or driven with an inserted
             driver. It is not designed for rotation by the thumb and fingers. A
             locking feature may be incorporated in the design of the head or
             threads.
