Abstract

A threaded fastener has opposite hand threads provided thereon for securing two components together, such as a companion flange and a flange yoke assembly that is used in a vehicular drive train system. The companion flange includes a hollow cylindrical sleeve portion and a disc-shaped flange portion having an aperture formed therethrough. The flange yoke includes a disc-shaped flange portion and a yoke portion having an aperture formed therethrough. The flange yoke aperture is aligned with the companion flange aperture. A threaded fastener extends through the companion flange aperture and the flange yoke aperture. The threaded fastener includes a first threaded portion having a first hand that is disposed within the companion flange aperture. The threaded fastener further includes a second threaded portion having a second hand that is disposed within the flange yoke aperture. The first hand is opposite to said second hand such that when a nut is screwed onto the threaded fastener to secure the companion flange and flange yoke together, the threaded fastener is effectively prevented from rotating.
