5315-14-479-2720 5315144792720 144792720 is a headless, generally cylindrically-shaped item having a straight, smooth, solid body, with or without a drilled hole(s). it has an outside diameter equal to or less than its length. its length must not exceed twelve inches (304 mm); for items whose length exceeds twelve inches (304 mm); see rod,straight,headless. it is used for aligning or transfer of torque and/or thrust, by fitting into corresponding holes of another item. see also pin,straight,threaded.

5315-14-521-2361 5315145212361 145212361 is a headed, cylindrically-shaped metal item having a shank and/or shoulder offset from the geometric center of the head. if shouldered, a portion of the shank and/or shoulder may be concentric with the head.

3040-14-521-2364 3040145212364 145212364 is an axle having two or more different diameters (greater than 0.031 inches (0.79 millimeter)) along its length. it must have one or more of the following conditions: a specified surface finish designation in the range 1 to 125 microinches (0.025 to 3.2 micrometers), periphersl flat(s), circular groove(s), keyway(s), splines, threads, or holes. the ends and/or sholders may be machined to accommodate bearings couplings and the like. it is not designed for use in aligning by fitting into corresponding holes of another item. for items used to transmit motion see shaft(1), shoulder. for items not having any of the above conditions see pin, shoulder, headless. excludes shaft(1),straight; and axle(1), straight.

5310-14-521-2365 5310145212365 145212365 is a washer having a centrally located hole with a solid or laminated cross-section and two flat parallel bearing surfaces. the hole must be 75 percent or less than the largest dimension and the bearing surface finish is greater than 32 microinch (0.8 micrometer). the thickness cannot exceed 25 percent of the largest outside dimension. when the largest outside dimension is less than 1/4 inch or 6mm, the thickness must be 0.006 inches (0.15mm) or greater and for items 1/4 inch (6mm) or larger, the thickness must be 0.016 inches (0.4mm) or greater. the maximum tolerance is applied to dimensions and used as a determining factor. items with separable lamination use shim. for items fabricated from ceramic or electrically rated materials by specification or industry standards use insulator (1), washer. excludes disk, valve, graphite impregnated and lubricated items.
