Abstract
Abstract A nut and panel assembly in which the nut has a pilot portion extending above outwardly directed flanges with undercut grooves in said flanges adjacent opposed sides of nut pilot portion. The assembly is produced by piercing the panel with the pilot portion of the nut and displacing the portions of the panel disposed above the undercut grooves into the grooves to fill the bottom portion of the grooves while maintaining a continuous connection between the deformed portions of the panel in the bottom of the grooves with the remainder of the panel.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
192 words
A nut and panel assembly comprising a nut and a panel, said nut having a rectangular pilot portion with flanges extending outwardly from opposed sides of said pilot portion and defining surfaces spaced below the free end of said pilot portion and means defining grooves in said surfaces adjacent said opposed sides, said means including bottom walls spaced below said surfaces, upwardly inner and outer side walls extending to said surfaces to define restricted openings along at least the length of the opposed sides of said pilot portion, said panel having aperture edges defined by piercing said panel with said nut pilot portion with a main portion of the panel bottomed on said surfaces, and first portions deformed around edges defined between said surfaces and said outer side walls in engagement with said outer side walls, and panel further having second portions between the aperture edges adjacent said opposed sides which are deformed to engage substantially the entire bottom and inner side walls of said grooves whereby to mechanically join said nut and said panel, said first panel portion and said second panel portion integral and continuous with said main panel portion.
Claim 2
Dependent Claim
192 words
A nut and panel assembly comprising a nut and a panel, said nut having a rectangular pilot portion with flanges extending outwardly from opposed sides of said pilot portion and defining surfaces spaced below the free end of said pilot portion and means defining grooves in said surfaces adjacent said opposed sides, said means including bottom walls spaced below said surfaces, upwardly inner and outer side walls extending to said surfaces to define restricted openings along at least the length of the opposed sides of said pilot portion, said panel having aperture edges defined by piercing said panel with said nut pilot portion with a main portion of the panel bottomed on said surfaces, and first portions deformed around edges defined between said surfaces and said outer side walls in engagement with said outer side walls, and panel further having second portions between the aperture edges adjacent said opposed sides which are deformed to engage substantially the entire bottom and inner side walls of said grooves whereby to mechanically join said nut and said panel, said first panel portion and said second panel portion integral and continuous with said main panel portion.
Claim 3
Dependent Claim
196 words
In a nut and panel assembly, including a nut having a rectangular pilot portion extending above a continuous surface surrounding said pilot portion and said surface spaced below a free end thereof, said surface having a continuous groove adjacent the sides of said pilot with portions of said groove on opposite sides of said pilot having upwardly and inwardly inclined inner and outer side walls continuous through said groove portions, said outer side wall merging with said surface to define restricted openings on opposed sides and portions adjacent the remaining sides having parallel inner and outer walls, said panel having aperture edges defined by piercing said panel with said nut pilot portion with a main portion of the panel bottomed on said surface, and first portions deformed around edges defined between said surface and said outer side wall in engagement with said outer side wall, said panel further having second portions between the aperture edges adjacent said opposed sides which are deformed to engage substantially the entire bottom and inner side walls of said restricted opening groove portions, spaced from said free end of the pilot portion, whereby to mechanically join said nut and said panel.
Claim 4
Dependent Claim
196 words
In a nut and panel assembly, including a nut having a rectangular pilot portion extending above a continuous surface surrounding said pilot portion and said surface spaced below a free end thereof, said surface having a continuous groove adjacent the sides of said pilot with portions of said groove on opposite sides of said pilot having upwardly and inwardly inclined inner and outer side walls continuous through said groove portions, said outer side wall merging with said surface to define restricted openings on opposed sides and portions adjacent the remaining sides having parallel inner and outer walls, said panel having aperture edges defined by piercing said panel with said nut pilot portion with a main portion of the panel bottomed on said surface, and first portions deformed around edges defined between said surface and said outer side wall in engagement with said outer side wall, said panel further having second portions between the aperture edges adjacent said opposed sides which are deformed to engage substantially the entire bottom and inner side walls of said restricted opening groove portions, spaced from said free end of the pilot portion, whereby to mechanically join said nut and said panel.
