6680-17-106-6437 6680171066437 171066437 is an instrument for measuring the rate of flow of a fluid through a pipeline. this measurement is indicated on a graduated scale either by means of a float confined in a tube, or pointer connected to a vane, or piston and spring or the like. excludes meter, fluid flow indicating, differential pressure; meter, fluid flow indicating, electromagnetic; and meter, fluid flow indicating, ultrasonic.

6210-00-395-6811 6210003956811 003956811 is a transparent or translucent item designed to enclose or be placed in front of a light source. sections of the lens may be opaque. it may or may not include a holder. it is designed to be either a replacement unit for a specific type of light, such as light, indicator&#59; light, navigational, marine&#59; stop light, vehicular&#59; and lantern, electric or that portion of a switch, (as modified) used as an actuator and having provisions for illumination. see also, window, lighting fixture&#59; globe&#59; electric light&#59; and filter (2), (as modified).

5306-01-075-8531 5306010758531 010758531 is 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.

4820-01-424-2666 4820014242666 014242666 is a valve having a flat or tapered disk (gate) which moves transversely to the axis of flow by rotating or sliding movements of the stem to open or close the orifice. it may also contain an oval or rectangular shaped slide which may be manually, motor, or pressure operated through the means of an arm or arm assembly. the body flange may be designed to accommodate tube type connectors. it may or may not contain thermal relief features. includes valve (gate) specifically designed for the control of fluid systems in aircraft or missiles.
