Options please ... installing an extension box onto an exterior wall
outlet (a weather proof cover will then be attached). The screw that
secures the outlet, also secures the extension box in place. While
securing the second screw I discover that the screw hole on the conduit
box is stripped ... I can not get a tight seal (one one screw holding)
and it will be impossible to get a weather tight seal on the cover
(which is attached to the extension box). The screw used is a 6 - 32
machine thread 2.5 inches long. Is there a quick fix ...

I have used a #6 self tapping screw in similar situations.
