PNEUMATIC COLLAR INSTALLATION TOOL Abstract of the Invention A pneumatic collar installation tool has a plunger assembly which advances from a retracted position near the rear of the tool through a collar pickup station to an extended position extending from the front of the tool. A collar shuttle delivers a collar or nut in front of the plunger assembly before it reaches the collar pickup station and retracts away from the collar pickup station before the plunger assembly moves through that station. The collar is picked up on an assembly that includes a split spring ring which engages the bore of the collar. The spring ring is mounted on a fixed member, which also includes a hexagonal key for preventing rotation of a bolt as the collar is threaded onto it. A rotating collar driver moves over the outside of the collar picked up by the collar pickup assembly for threading the collar onto a bolt.
