ABSTRACT:
In one embodiment of the present invention a fastener assembly comprises a first and second bushing that are each inserted into respective parts to be coupled. The first bushing has a bearing post member extending from its mating face. The bearing post member has two circumferential locking flanges spaced along its length. The second bushing member has an axially-extending opening to receive the bearing post member. The opening has two reduced diameter sections situated to coincide with the circumferential locking flanges when the bearing post member is inserted into the opening. The reduced diameter sections are in snap-fit engagement with the circumferential locking flanges to resist separation of the first and second bushing members. Fastener stability and strength is increased by requiring a fixed dimensional relationship between the length of the bearing post member and the effective radial gap existing between the post member and the opening in the second bushing member when the post member is inserted therein. Fastener "slop" is further reduced by requiring another fixed dimensional relationship between the effective diameter and the length of the bearing post member. Variations on this embodiment are described, including a separate bearing post member that is statically attached to the first bushing member, a sleeve detachably connecting the interconnecting portions of each bushing to their respective lead end portions, and a wedge to expand the outer surface of each bushing within their respective bores.
