Code Translation
AASB The dimension, measured along a line parallel to the longitudinal axis, from the largest bearing surface of the fastener head to the extreme opposite end, or as specifically designated for other type fasteners.
CBBL Those features, not otherwise specified, which may be required for proper functioning of the item.
ANEE A measurement of the longest dimension of the grip, in distinction from width.
CQFM A numeric value that reflects the hardness of an item when used in conjunction with a hardness rating scale.
AASU A measurement from the bottom to the top of the head, in distinction from depth.
AASK The style designation indicating the configuration that most nearly corresponds to the appearance of the head.
MATT The chemical compound or mechanical mixture properties of which the item is fabricated.
CQBC The maximum rated load in tension applied in a longitudinal direction, per unit of cross-sectional area, that the material can withstand without rupture.
AHYM The nominal length of a straight line which passes through the center of the threaded portion, and terminates at the circumference.
MDCL The specification, standard, or manufacturers reference, and the classification designation, such as class, condition, temper, and the like, that identifies the material.
CSYM Designates the specific surface roughness rating, representing the arithmetic average deviation of the surface from the meanline in profile.
CSYM Designates the specific surface roughness rating, representing the arithmetic average deviation of the surface from the meanline in profile.
STDC The specification, standard, or manufacturers reference, and the classification designation, such as type, class, grade, and the like, that identifies the surface treatment material.
SFTT The metallic, nonmetallic, and/or chemical properties with which the item is plated, dipped, and/or coated.the treatment is designed to protect the surface(s) and cannot be wiped off.
AAJD A numeric-alpha designator indicating the pitch diameter tolerance and an external or internal thread.
AAJF The direction of the thread when viewed axially. a right-hand thread winds in a clockwise direction while a left-hand thread winds in a counterclockwise direction.
AASA A measurement of the extent of threads, including incomplete threads, along a line parallel to the longitudinal axis.
CMLP The number of threads on the item per linear inch measured on a line parallel to the thread axis.
THSD A designation distinguishing one group of thread diameter-pitch combinations from another by the number of threads per measurement scale for a specific diameter.

Technical Definition

Bolt, Machine, also referenced with federal logistics item name code 01847 - An externally threaded fastener designed for insertion through holes in assembled parts and normally intended to be tightened or released by torquing a nut. the threaded and unthreaded portions are both of one nominal diameter of 0.190 inch (5 mm) or larger. the head is not designed to be held or driven with an inserted driver or by the thumb and fingers. a locking feature may be incorporated in the design of the head or threads. head dimensions and sizes of threaded and unthreaded portions shall conform to internationally recognized fastener standards. for items having a grip length portion machined to a tolerance of 0.0015 inch (0.038 mm) or less, bolt, shear. see also screw, cap, hexagon head and screw, machine.
