Pre-assembled manifold fastener system and method therefor

摘要

A pre-assembled workpiece fastenable to a mounting surface of a second workpiece, and in one application a pre-assembled plastic component fastenable to a metal automotive engine component. The pre-assembled workpiece includes an opening extending therethrough between an outer surface and a mounting surface thereof. A sleeve member is retainably disposed in the opening through the pre-assembled workpiece, and a fastener having a threaded shank portion and a head is retainably disposed through the sleeve member. The fastener is axially and laterally positionable relative to the pre-assembled workpiece, whereby the pre-assembled workpiece is mountable and alignable on the mounting surface of the second workpiece without interference from the fastener. The sleeve member includes a resilient first substantially radial flange member, whereby the sleeve member is axially positionable relative to the opening through the pre-assembled workpiece upon fastening the pre-assembled workpiece to the second workpiece to compensate for misalignment tolerance and thermal expansion of the pre-assembled workpiece.
