ITEM NAME:   BOLT,CLOSE TOLERANC
DEFINITION:  An externally threaded fastener whose unthreaded portion is of a
             specified 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
             nominal major diameter of the threads shall be at least one thousandth
             (0.001) of an inch (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 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. For items having close tolerance, and
             fabricated from material having 160,000 pounds per square inch (1100
             megapascals) minimum tensile strength, see BOLT, SHEAR. For items
             fabricated from material having less than 160,000 pounds per square
             inch (1100 megapascals) minimum tensile strength and not having a
             close tolerance, see BOLT, MACHINE.
