A screw, machine or screw, cap, socket head whose unthreaded portion is of specified grip length, plated or unplated, and is machined to a tolerance of one thousandth (0.001 in.) (0.025 mm) or less of a specific diameter for items (1.000 in.) (25 mm) or less in diameter. Items over (1.000 in.) (25 mm) in diameter shall have a tolerance of fifteen ten thousandths (0.0015 in.) (0.038 mm) or less. The nominal major diameter of the threads shall be at least one thousandth (0.001 in.) (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 designed to be held or driven with an inserted driver. It is not designed for rotation by the thumb and fingers. A locking feature may be incorporated in the design of the head or threads.

Details
A numeric-alpha designator indicating the pitch diameter tolerance and an external or internal thread.Details
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.Details
A measurement of the extent of threads,including incomplete threads,along a line parallel to the longitudinal axis.Details
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.Details
The style designation indicating the configuration that most nearly corresponds to the appearance of the head.Details
The length of a straight line which passes through the center of a circular head,and terminates at the circumference.Details
A measurement from the bottom to the top of the head,in distinction from depth.Details
The length of a straight line which passes through the center of the grip,and terminates at the circumference.Details
The style designation indicating the configuration that most nearly corresponds to the appearance of the internal drive.Details
The nominal length of a straight line which passes through the center of the threaded portion,and terminates at the circumference.Details
A measurement of the longest dimension of the grip,in distinction from width.Details
The number of threads on the item per linear inch measured on a line parallel to the thread axis.Details
The included angle of the countersink.Details
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 on one or more other functions.Details
The chemical compound or mechanical mixture properties of which the item is fabricated.Details
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.Details
A designation distinguishing one group of thread diameter-pitch combinations from another by the number of threads per measurement scale for a specific diameter.| Part | CAGE | DAC | HCC | RNCC | RNVC | MSDS | RNAAC |
