Characteristic Codes

NAS1303-86 spec. code meanings
Code Translation
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.
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.
AASK The style designation indicating the configuration that most nearly corresponds to the appearance of the head.
AASU A measurement from the bottom to the top of the head, in distinction from depth.
AAUR The length of a straight line which passes through the center of the grip, and terminates at the circumference.
AHYM The nominal length of a straight line which passes through the center of the threaded portion, and terminates at the circumference.
ANEE A measurement of the longest dimension of the grip, in distinction from width.
CMLP The number of threads on the item per linear inch measured on a line parallel to the thread axis.
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.
CQFM A numeric value that reflects the hardness of an item when used in conjunction with a hardness rating scale.
MATT The chemical compound or mechanical mixture properties of which the item is fabricated.
MDCL The specification, standard, or manufacturers reference, and the classification designation, such as class, condition, temper, and the like, that identifies the 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.
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.
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.
ZZZK The document designator of the specification or standard which established the item of supply.

Technical Definition

Bolt, Shear, also referenced with federal logistics item name code 15903 - 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.
