Abstract: The present invention provides an in-line valve cartridge for use in sanitary fittings. The valve cartridge of the present invention includes a generally cylindrical housing having a proximate extent for support in a sanitary fitting, a distal extent from which water leaves the cartridge and a longitudinal body extending therebetween. The body has a thickness delineated by inner and outer peripheral surfaces with the inner peripheral surface further defining an elongated lumen thereby. The housing further includes an annular aperture that accommodates placement of a driving member therethrough and includes opposing extents that operate as stops for the driving member and correspond to the valve cartridge's open and closed positions. In addition, rotating and stationary ceramic disks are disposed in tandem wherein the stationary disk has at least one aperture for through flow of cold water, hot water or a combination thereof.

Abstract: A fastener for use with inch and metric wrenches has a body unitarily formed with at least one screwthread, a pair of concentric faceted tool-fitting regions of different sizes, and a step between the regions. One of the regions corresponds to a metric wrench size and the other of the regions corresponds to an inch wrench size. The screwthread and both regions are coaxial.
