ITEM NAME:   BOLT,SHEAR
DEFINITION:  A high strength, 160,000 pounds per square inch (1100 megapascals)
             minimum tensile strength externally threaded fastener designed for use
             in applications involving great shear stress. The head is designed to
             accommodate an external wrench or driver. 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. 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
             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. A locking feature may be incorporated
             in the design of the head or threads. See BOLT, MACHINE and BOLT,
             CLEVIS.
