Pin and grommet fastener accommodating two directional offset and related methods

A pin and grommet fastener for coupling a first component and a second component together, the pin and grommet fastener comprising:

• a pin including a pin retention groove or protrusion;
• a grommet comprising:
• an inner housing defining a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction and with a cooperating pin retention groove or protrusion operable to retain the pin retention groove or protrusion, and the inner housing having a pair of inner housing retaining surfaces;
• and
• an outer housing defining an interior, and the outer housing having an outer housing flange, and a pair of cooperating inner housing retaining surfaces, and a plurality of resilient retention wings positioned to retain the first component with the outer housing flange when the outer housing is mounted within an aperture of the first;
• component,
• wherein the pair of inner housing retaining surfaces engage the pair of cooperating inner housing retaining surfaces, with the pin retaining receptacle of the inner housing extending into the interior of the outer housing, to slidably couple the inner housing and the outer housing together while permitting movement of the inner housing relative to the outer housing in a Y-direction in response to the inner housing moving in the Y-direction during insertion of the pin into the pin retaining receptacle, and
• wherein each of the pair of cooperating inner housing retaining surfaces of the outer housing are provided by a protrusion extending from a post of the outer housing.
