ABSTRACT:
A flexible plastic grommet is received in an aperture of an internal combustion engine with the multiple purposes of frictionally engaging the gasket to prevent separation, locating the gasket with respect to separate but communicating components, and retaining a threaded fastener in the grommet which is used to join the mechanical components. The grommet comprises a sidewall with a plurality of symmetrically spaced circumferentially disposed grooves that extend longitudinally along the grommet. An innermost periphery of the sidewall is defined by a base of each of the grooves while an outermost periphery of the sidewall extends circumferentially between each of the grooves. The innermost periphery and the outermost periphery of the sidewall comprise a plurality of locking projections extending radially away from the sidewall to promote frictional engagement between the grommet and the gasket, fastener, and the one of the mechanical components.
