Abstract:
A one-piece metallic threaded insert fixedly positionable into a carrier substrate to facilitate securement with respect thereto comprising:A) a main body being generally cylindrically shaped and defining a central bore defining interior threads therealong and extending axially therethrough, said main body defining a central axis extending axially through said central bore, said main body defining an outer surface outwardly facing therearound and an interior surface within said central bore, said main body defining an upper end and a lower end with said central bore extending axially therebetween; B) a plurality of outer ring members located on said outer surface of said main body and extending outwardly therefrom and therearound, said outer ring members including a knurled portion thereon to facilitate securement of said main body with respect to the carrier substrate responsive to insertion of the one-piece metallic threaded insert therewithin, said outer ring members defining at least one outer annular slot therebetween to allow said carrier substrate material to migrate thereinto to further facilitate securement of said main body with respect to the carrier substrate; C) an upper pilot ribbed portion positioned on said outer surface of said main body adjacent said upper end thereof to facilitating placement thereof into the carrier substrate during implanting of the one-piece metallic threaded insert thereinto, said upper pilot ribbed portion defining an upper leading surface which is arcuate for further facilitating insertion of the one-piece metallic threaded insert into the carrier substrate with the upper end being inserted firstly; and D) a lower pilot ribbed portion positioned on said outer surface of said main body adjacent said lower end thereof to facilitating placement thereof into the carrier substrate during implanting of the one-piece metallic threaded insert thereinto, said lower pilot ribbed portion defining a lower leading surface which is arcuate for further facilitating insertion of the one-piece metallic threaded insert into the carrier substrate with the lower end being inserted firstly in order to allow the one-piece metallic threaded insert to be capable of being inserted with said upper end entering first or with said lower end entering first.
