The system further includes a driver for driving the fastener through the sleeve bore and into the base, the driver including a nozzle having a bore for receiving the fastener, the nozzle being adapted to enter the sleeve countersink. The driver further includes a hammer disposed in the nozzle and movable to engage the head of the fastener and to drive the fastener into locking engagement with the base, to fix the sleeve to the base, and thereby fix the structural members to the base. ## Claims ### Claim 1 A fastening system for anchoring wood floors to a base, the system comprising: a fastener having a shank, a pointed distal end, and a proximal head end having an enlarged diameter head with a proximal surface; a sleeve for retaining structural members of the floor, said sleeve having a central bore therethrough, a countersink extending distally from a proximal end of said sleeve and coaxially with the bore, and an annular flange extending outwardly from the sleeve proximal end; and a driver for driving said fastener through the sleeve countersink and the sleeve bore and into the base, said driver comprising a nozzle having a bore for receiving said fastener, the nozzle being adapted to enter the sleeve countersink, said driver further comprising a hammer disposed in the nozzle and movable to engage the proximal surface of the head of said fastener and to drive said fastener into locking engagement with the base, to fix said sleeve to the base, and thereby fix the structural members to the base. ### Claim 2 (depends on 1) The fastening system in accordance with claim 1 wherein the fastener shank is provided with a distal portion having a diameter about equal to a diameter of the sleeve central bore, a proximal portion having a diameter larger than the diameter of the shank distal portion and the diameter of the sleeve central bore. ### Claim 3 (depends on 1) The fastening system in accordance with claim 1 wherein said driver further comprises a spring-biased safety rod having a distal end engageable with the sleeve annular flange and movable thereby against the spring-bias to place said driver in firing condition. ### Claim 4 (depends on 1) The fastening system in accordance with claim 1 wherein said driver further comprises a magazine for retaining a plurality of fasteners therein and for serially feeding the fasteners to said nozzle for the engagement with said hammer. ### Claim 5 (depends on 1) The fastening system in accordance with claim 1 wherein the structural members comprise at least one elongated board having therein a plurality of holes, each hole having a counterbore defining an annular surface in the hole, the boards each being supported by resilient pads mounted on the base, the sleeve flange being configured such that the annular surface in the board hole is engaged by the sleeve annular flange at about the same time as the base is engaged by a bottom end surface of the sleeve upon insertion of the sleeve into the board hole. ### Claim 6 (depends on 5) The fastening system in accordance with claim 5 wherein upon driving of said fastener by said hammer, the head of said fastener engages with a bottom end wall of the sleeve countersink and proceeds no further, whereby to connect the sleeve and board to the base without compressing the pads. ### Claim 7 (depends on 5) The fastening system in accordance with claim 5 wherein an axial extent of the sleeve annular flange is less than the axial extent of the board hole counterbores. ### Claim 8 (depends on 7) The fastening system in accordance with claim 7 wherein said at least one board has an upper surface and a lower surface, and the overall length of said sleeve is less than a distance between said upper and lower surface. ### Claim 9 (depends on 8) The fastening system in accordance with claim 8 wherein an axial length of said sleeve, less the axial length of the sleeve flange, is equal to a distance between the counterbore annular surface of said at least one board and the lower surface of said at least one board. ### Claim 10 (depends on 1) The fastening system in accordance with claim 1 wherein the sleeve central bore is sized to accommodate the fastener shank and the sleeve countersink is sized to receive the nozzle of said driver. ### Claim 11 (depends on 10) The fastening system in accordance with claim 10 wherein the holes in the board are about 0.040 inch to about 0.060 inch larger than an outside diameter of the sleeve. ### Claim 12 (depends on 1) The fastening system in accordance with claim 1 and further comprising a washer disposed inside the sleeve countersink in engagement with a countersink bottom end wall, the washer being engageable by the fastener head when the fastener is driven into the base.
