Claim 1
Independent Claim
305 words
A nut and panel assembly, comprising: an integral metal nut having one end abutting one face of said panel and a passage extending through said nut having an axis generally normal to said panel face, said nut passage including an enlarged chamber located adjacent said panel terminating in a generally cylindrical threaded bore having a diameter smaller than the maximum radial dimension of said chamber, said chamber having a first portion adjacent said panel face and a second portion adjacent said threaded bore, said first chamber portion having a greater diameter than said second chamber portion, radially projecting antirotation means located within said first chamber portion, said panel having a portion engaging said nut end, a tubular panel portion displaced radially and axially within said first chamber portion and projecting axially within said second chamber portion, said tubular panel portion terminating in an opening coaxially aligned with said nut bore, the exterior surface of said tubular panel portion engaging the surface of said radially projecting antirotation means preventing relative rotation between said panel and said nut, the interior surface of said tubular panel portion within said second chamber portion having a female thread, said female thread having a pitch diameter substantially equal to the pitch diameter of said nut bore, the interior surface of said tubular panel portion within said first chamber portion having a greater internal diameter than said threaded tubular portion, a self-threading male threaded member having a pitch diameter generally equal to the pitch diameter of said threaded nut bore, said male threaded member threadably received in said threaded tubular portion within said second chamber portion but spaced from said internal wall of said tubular portion within said first chamber portion and said first chamber portion extending axially a distance equal to at least one full thread of said male threaded member.
