A fastening tool with a housing, a nosepiece that is coupled to the housing and a contact trip that includes a lower contact trip, an upper contact trip and a depth adjustment assembly. The lower contact trip is mounted on the nosepiece for translation between an extended position and a retracted position. The upper contact trip is separate from the lower contact trip. The depth adjustment assembly includes a stem, a sleeve that is threadably coupled to the stem, and a knob. The knob is rotatably coupled to the sleeve but axially movable thereon. The stem is coupled to one of the lower contact trip and the upper contact trip and the sleeve is captured by the other one of the lower contact trip and the upper contact trip.

1. A fastening tool comprising:a housing; a nosepiece coupled to the housing; and a contact trip having a lower contact trip, an upper contact trip and a depth adjustment assembly, the lower contact trip being mounted on the nosepiece for translation between an extended position and a retracted position, the upper contact trip being separate from the lower contact trip, the depth adjustment assembly including a stem, a sleeve, and a knob, the stem being threadably coupled to the sleeve, the knob being rotatably coupled to the sleeve but axially movable thereon, wherein the stem is coupled to one of the lower contact trip and the upper contact trip and wherein the sleeve is captured by the other one of the lower contact trip and the upper contact trip. 2. The fastening tool of claim 1, wherein the depth adjustment assembly further comprises an adjustment housing, the adjustment housing being coupled to the housing and including a first set of protrusions and a second set of protrusions that cooperate to limit an amount by which the knob may translate relative to the housing.3. The fastening tool of claim 2, wherein the adjustment housing includes at least one element that is coupled to the housing and which extends toward the knob to hold the knob.4. The fastening tool of claim 3, wherein the at least one element is movable in response to manual rotation of the knob.5. The fastening tool of claim 3, wherein the knob includes an outer surface with a plurality of peaks and valleys formed thereon.6. The fastening tool of claim 5, wherein the at least one element is biased toward the outer surface of the knob and deflects outwardly therefrom in response to manual rotation of the knob.7. The fastening tool of claim 6, wherein the at least one element is a finger that is integrally formed with the adjustment housing.8. The fastening tool of claim 1, the other one of the lower contact trip and the upper contact trip include a pair of spaced apart end walls between which the sleeve is disposed.9. The fastening tool of claim 8, wherein the sleeve includes at least one necked down portion that defines a flange that abuts one of the end walls, the necked down portion being received into a slotted aperture that is formed in the one of the end walls.10. The fastening tool of claim 1, wherein the knob has a non-circular central aperture into which the sleeve is received.11. The fastening tool of claim 1, wherein the stem includes an attachment portion that is removably coupled to the one of the lower contact trip and the upper contact trip.12. The fastening tool of claim 11, wherein the attachment portion includes a flange and a threaded end section.13. The fastening tool of claim 1, wherein a spring arm is coupled to one of the lower contact trip and the upper contact trip and wherein a spring is disposed between the housing and the spring arm, the spring biasing the lower contact trip into the extended position.14. The fastening tool of claim 1, further comprising a frictional element coupled to one of the stem and the sleeve and frictionally engaging the other one of the stem and the sleeve to resist relative rotation between the stem and the sleeve.15. The fastening tool of claim 14, wherein the frictional element is an O-ring.16. A fastening tool comprising:a housing; a nosepiece coupled to the housing, the nosepiece; and a lower contact trip that is configured to translate relative to the nosepiece; an upper contact trip that is separate from the lower contact trip; and a depth adjustment assembly for adjustably coupling the lower contact trip and the upper contact trip, the depth adjustment assembly including a stem, a sleeve, a knob and an adjustment housing, the stem having a threaded adjustment portion and an attachment portion that is removably coupled to one of the lower contact trip and the upper contact trip, the threaded adjustment portion of the stem being threadably engaged to the sleeve, the sleeve including a pair of flanges that are disposed between opposite end walls of the other one of the lower contact trip and the upper contact trip, the knob including a central aperture having a non-circular shape that corresponds to at least a portion of the sleeve to rotatably couple the knob and the sleeve but permit the sleeve to translate axially through the knob, the adjustment housing being coupled to the housing and axially capturing the knob, the adjustment housing carrying at least one deflectable member that is movable between a first position, which inhibits free rotation of the knob, and a second position, which permits the knob to be manually rotated. 17. The fastening tool of claim 16, wherein the at least one deflectable member includes a finger having a proximal end that is coupled to the adjustment housing.18. The fastening tool of claim 17, wherein the knob includes an outer surface with a plurality of peaks and a plurality of valleys formed thereon.19. The fastening tool of claim 18, wherein the finger does not contact the knob when a distal end of the finger is disposed in one of the valleys.20. The fastening tool of claim 16, wherein the stem further includes first stop for limiting an amount by which the threaded adjustment portion may be threaded into the sleeve and a second stop for limiting an amount by which the threaded adjustment portion may be threaded out of the sleeve.21. The fastening tool of claim 20, wherein at least one of the first and second stops is integrally formed with the stem.22. The fastening tool of claim 16, wherein the stem is generally, L-shaped.
