Abstract: A drain valve for an oil pan of a vehicle lubrication system includes an aperture and a drain plug. The drain plug is rotatable relative to the aperture between closed and opened positions with less than a full rotation of the plug. The plug remains secured to the aperture even when the valve is opened.

Abstract: A fastener system having a fastener and a fastener retention member is provided. The fastener includes a threaded portion, a head, and a shank portion extending therebetween. The threaded portion includes threads having a major diameter greater than a diameter of the shank portion. The fastener retention member includes a body member having an axial opening therethrough, and at least one shank engagement member protruding into the axial opening of the body member. The shank engagement members define a diameter smaller than the major diameter of the threads of the threaded portion of the fastener. The shank portion of the fastener is received in the axial opening of the fastener retention member and is axially movable therein and trapped between a position where the head of the fastener abuts the fastener retention member and a position where the threaded portion of the fastener engages the shank engagement members.

Abstract: A threaded fastener having a threaded shaft with a head disposed on a portion thereof and a deflectable flange protruding outwardly from the shaft at or near the head. The deflectable flange has a generally concave surface facing toward a leading end of the fastener shaft. A protuberance is disposed on the shaft and spaced apart axially from the generally concave surface of the deflectable flange to limit compression of a fixture clamped between the fastener head and a work surface.
