ABSTRACT:
A plastic encapsulated nut and washer assembly includes a plastic retainer or body for holding a hex nut and washer in axially aligned abutting relation ready for assembly with an external threaded member. A portion of the plastic retainer provides an annular seal around the washer when the nut is tightened on a threaded member and an extension bore is formed in the plastic material for providing a lock-nut function when the threaded member is extended into the extension bore from the threaded bore of the hex nut.
