Claim 10:
11. A weld nut assembly, comprising:
an annular flange structure;
an annular body structure coupled to the annular flange structure;
an annular washer coupled to a bottom portion of the annular flange structure opposite the annular body structure;
an annular ring projection comprising a triangle structure protruding from the annular washer opposite the annular body structure, wherein the annular ring projection protruding from the annular washer opposite the annular body structure is disposed around an outer periphery of the annular washer opposite the annular body structure; and
a plurality of circumferential weld protrusions each comprising a triangle structure protruding from the annular washer and the annular ring projection opposite the annular body structure, wherein the plurality of circumferential weld protrusions protruding from the annular washer and the annular ring projection opposite the annular body structure are evenly spaced about the annular ring projection,
wherein the annular flange structure and the annular body structure collectively define an inner bore, wherein a portion of the inner bore defined proximate the annular flange structure has a variable diameter, a portion of the inner bore defined proximate the annular flange structure defines threads adapted to pull a screw into the inner bore, and a portion of the inner bore defined proximate the annular body structure defines a smooth internal surface adapted to lock the screw in the inner bore.
