The workpiece engaging nose body includes a nose portion (24) and a rear portion (22) with the nose portion slidably mounted on the rear portion for movement rearwardly when the nose is urged into a workpiece to drive a screw. An exitway (87) is defined between the nose portion and rear portion through wich spent strap from wich screws have been driven exit the nose body. On urging the nose body into the workpiece, the nose portion slides rearwardly to engaged the strap in the exitway and move it rearwardly into engagement with the rear portion in the exitway. The strap is preferably "pinched" in the exitway between the nose portion and rear portion to assist in locating a screw to be driven from the nose body.
