ABSTRACT:
An improved fastener assembly (10) for securing a rocker arm cover (11) to an engine block (13) is described. In the preferred embodiment, the fastener assembly is comprised of a bolt (15) with an unthreaded shaft (15b) between a head (15a) and a threaded end (15c) along a longitudinal axis of the bolt. The bolt is in a slideable relationship within a cylindrical opening (19a) through a grommet (19) and a secured washer (17). Projections or interference portions (15e) on the unthreaded shaft adjacent to the threaded section and opposite the head, restrict the axial movement of the bolt within the grommet and the washer. While the rocker arm cover is being alilgned on the engine block, the bolt is in an up position with the projecting surfaces adjacent to the washer. Once the rocker arm cover is aligned, the bolt is threadingly mated with a threaded aperture (13a) in the engine block. The amount of torque that can be applied to the bolt is controlled by a shoulder (15g) of the unthreaded shaft section contacting the engine block.
