5306-14-572-3050 5306145723050 145723050 is 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.

9530-01-343-6959 9530013436959 013436959 is a metallic product of ferrous or nonferrous material. it is produced as a solid section in straight lengths or short barlike forms of cored or solid cross section. it may be round, square, hexagon, oval, half-oval, or half-round shape whose width, diameter, or distance between parallel faces is 3/8 inch or 10.0mm or greater. rectangular shape cross-sectional dimensions are limited to those established in appendix c, fiig a131. it is round to a maximum diameter of 24 inches or 610.0mm. for a rectangular shape less than 3/32 inch or 2.5mm thickness, see wire (1), nonelectrical.

4710-12-196-3722 4710121963722 121963722 is a straight, hollow product, welded or seamless, of round, square, or any other cross section and continuous periphery, which does not conform in cross sectional dimensions to recognized pipe standards, or those in tables 1 through 10, appendix c, fiig a004a. it is designed to convey fluids, gasses, and/or semisolids. it may be rolled into coils for ease in handling. for items designed to join a tube or tube fitting to another tube, pipe, or hose or fitting, see adapter (as modified); coupling (as modified); or nipple (as modified). excludes tube, bent (as modified); pipe, metallic; spacer, sleeve; metal bar (hollow); and items with fittings, except end protectors.

9540-01-343-6963 9540013436963 013436963 is a structural shape fabricated from a ferrous or nonferrous material and resembling the letter l in cross-sectional form. the edges may have a bulb, be rounded, and the inside corner may have a fillet.

5970-21-849-4853 5970218494853 218494853 is a rigid or flexible tubing having uniform inside and outside diameters in the overall length. it is specifically designed to prevent any undesirable flow of current between conductors and other objects. includes shrinkable type tubing, items in bulk and in specific fabricated lengths (cut to size). excludes items not having rated electrical characteristics. also excludes bushing, sleeve; cable nipple, electrical; conduit (as modified); insulation sleeving, electrical, special purpose; insulation sleeving, thermal; sleeve, marker, cable; sleeving, textile, electrical; tubing, glass; and tubing, nonmetallic.
