ABSTRACT:
A locator dowel assembly for locating a fixture plate relative to a base plate. The assembly includes a bushing designed to be frictionally engaged in an opening in the fixture plate and define a central opening extending through the bushing and the fixture plate. A locator dowel with an elongated body has a tool engaging feature at one end. The locator dowel has a diameter slightly smaller than the diameter of the bushing to allow sliding movement therebetween. Stop and capture apparatus includes a longitudinally extending slot in the outer periphery of the locator dowel and a stop member positioned in the inner wall of the bushing and extending radially into the central opening. The stop member is engaged in the slot in the locator dowel and forms a stop to limit vertical movement of the locator dowel in the bushing and capturing the locator dowel in the bushing.
