The surgical fastener applier of claim 1, wherein the rotatable drive rod simultaneously extends through each of the plurality of fasteners. 14. A surgical fastener applier for ensuring proper seating of a fastener comprising: a housing;an actuation mechanism disposed in mechanical cooperation with the housing and defining a longitudinal axis;a drive mechanism operatively associated with the actuation mechanism;a rotatable center drive rod extending distally from the housing and configured to support a plurality of fasteners, the rotatable drive rod being at least partially radially surrounded by the plurality of fasteners;an axially translatable tubular sleeve coaxially disposed along at least a portion of the drive rod and configured to at least partially radially surround said plurality of fasteners; anda control system including at least one load measuring device supported in the housing, wherein the load measuring device is a load sensor, the control system being configured to activate a motor to allow movement of the drive mechanism once a predetermined load is equally distributed about the distal end of the tubular sleeve. 15. The surgical fastener applier of claim 14, wherein the tubular sleeve further comprises a plurality of radially spaced protrusions. 16. The surgical fastener applier of claim 14, further comprising a power source operatively connected to the control system. 17. The surgical fastener applier of claim 14, wherein the drive mechanism has a motor. 18. The surgical fastener applier of claim 14, further comprising a power supply operatively connected to the drive mechanism. 19. The surgical fastener applier of claim 14, wherein the drive mechanism is configured to eject a fastener of said plurality of fasteners from the surgical fastener applier. 20. The surgical fastener applier of claim 14, wherein a distal most end of the tubular sleeve extends distally past a distal most end of the drive rod prior to the distal end of the tubular sleeve being subject to said predetermined load. 21. The surgical fastener applier of claim 14, wherein the rotatable center drive rod is rotatable 360° about the longitudinal axis. 22. The surgical fastener applier of claim 14, wherein the rotatable center drive rod includes a longitudinally-extending slot therein, wherein the slot is configured to receive a portion of each of the plurality of fasteners. 23. The surgical fastener applier of claim 14, wherein the rotatable center drive rod simultaneously extends through each of the plurality of fasteners.
