Floating fastener mounting structure

A floating fastener mounting structure, comprising a metal panel member, a mounting socket affixed to said metal panel member, a lock screw mounted in said mounting socket, and a spring member mounted in said mounting socket to floatably support said lock screw in said mounting socket, wherein:

• said metal panel member comprises a mounting through hole, and a convex wall portion disposed around said mounting through hole and defining a bottom accommodation space;
• said mounting socket is upwardly inserted through said mounting through hole of said metal panel member and riveted to said metal panel member, said mounting socket comprising a center hole vertically extending through opposing top and bottom walls thereof for accommodating said lock screw and said spring member, an annular step extended around the outer perimeter thereof at a selected elevation, a stop flange extended around the outer perimeter of said mounting socket below said annular step, and a annular locating groove extended around the outer perimeter between said annular step and said stop flange, the outer diameter of said stop flange being larger than the outer diameter of said annular step, said annular step defining a downwardly and outwardly sloping top surface for guiding said convex wall portion of said metal panel member downwardly over said annular step into engagement with said annular locating groove.
