Characteristic Codes

AS194-5-22 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.
AAWB	The length of a straight line which passes through the center of the shank unthreaded hole, and terminates at the inside 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.
CQFM	A numeric value that reflects the hardness of an item when used in conjunction with a hardness rating scale.
CRZS	The distance from the shank hole centerline to the largest bearing surface of the head.
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.
FEAT	Those unusual or unique characteristics or qualities of an item not covered in the other requirements and which are determined to be essential for identification.
MATT	The chemical compound or mechanical mixture properties of which the item is fabricated.
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.

Technical Definition

Bolt, Close Tolerance, also referenced with federal logistics item name code 27851 - 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.
