1. A method of assembling a fastener system comprising: inserting a bushing having a smooth outer bore and a plurality of internal threads fully into a housing internal bore until a bushing shoulder contacts the housing and an end of said housing extends beyond said housing internal bore,placing a snap ring in a relief on an exterior of said bushing extending beyond the housing; andseating said ring against a shoulder within a piece. 2. The method of claim 1 further comprising the steps of: threading external threads of a bolt through said threads in said bushing, andpushing said external threads through said bushing. 3. The method of claim 2 further comprising: pushing said external threads through said piece. 4. A fastener system comprising: a bushing having internal threads and a snap ring relief;a reduced shank bolt having external threads in a threaded region;a snap ring;a housing having an internal bore and a recessed bore region;a piece adjacent said housing; andwherein, when the system is assembled, the snap ring prevents the bushing from being removed from the housing, and the last internal thread prevents the reduced shank bolt from being removed from the bushing by contacting a first male thread, and wherein the piece includes a shoulder that is adapted to accept and seat the snap ring in the piece. 5. A bushing for use in a fastener system including a housing, a piece adjacent said housing, a snap ring and a bolt with said snap ring seated in a shoulder in said piece, said bushing comprising: a body disposed along an axis, said body having a first end having a shoulder extending radially outwardly therefrom for engaging said housing;an outer surface having a relief therein, said relief configured to receive said snap ring,wherein the body defines a first bore having a first diameter extending a first distance along said axis from said first end, said first bore being threaded, and wherein a second bore extending from said first bore to a second end of said body, said second bore having a second diameter that is larger than said first diameter for allowing threads of said bolt to pass through said second bore without rotation. 6. A fastener assembly, said fastener assembly comprising: a housing having: a first length between a housing first end and a housing second end,a first bore disposed through said housing,a second bore disposed about said first bore, said second bore being wider than said first bore, wherein said second bore extends a first distance within said housing to said second end of said housing;a bushing having: a second length between a bushing first end and a bushing second end, wherein said second length is greater than said first length,an outer surface extending a second distance, said outer surface having a radially extending ring disposed within a relief therein, said ring and said bushing translatable axially within said second bore and translatable axially beyond said second end of said housing; anda piece adjacent said housing, said piece having a third bore receiving said bushing outer surface,a fourth bore that is wider than said fourth bore diameter, and,a shoulder between said third bore and fourth bore against which said ring sits if translated axially beyond said second end of said housing. 7. The fastener assembly of claim 6 wherein a gap is provided between said piece and said housing if said ring is seated against said shoulder. 8. The fastener assembly of claim 6 further comprising a bolt having a threaded bore and a smooth bore extending from said threaded bore to a head, said bolt having a length that extends said threaded end through said bushing said housing and said piece.
