The chuck assembly has a hollow housing 29, a tubular portion 36 and a fastener retaining head portion 32 having a retaining seat opening 38. Portion 32 comprises lips 40 movable apart against leaf springs 42. Housing 29 is slidable on a torque limiting device 48 and is held non-rotatable therewith by pins 52 and slots 54. A screw magazine comprises a base 61, a flexible membrane 63 and a cap 65 which have aligned passages therein and are indexably mounted in a housing 90. The magazine is driven by a ratchet wheel 100 which is itself driven via a trigger finger 110. Finger 110 is moved by chuck assembly 26 when, in its rearward position during a fastening operation, it moves plunger 114 rearwardly which in turn operates the finger via balls 116. Spring 132 returns finger 110 to its start position and a pawl 133 cooperates with notches 85 and 77 to stop any return movement of the magazine. Screws are retained in the magazine by the membrane 63, until a screw advancing assembly 66 comes into affect. This assembly comprises an ejector member 138 slidably mounted in a sleeve 144 and having a U-shaped extension 170. At its forward end member 138 has a flange 148 to which an abutment rod 152 is attached. This rod 152 projects through a guide wall 146 and engages a block 156. As chuck assembly 26 initially moves rearwardly block 156 is moved rearwardly by spring 160. This allows a spring in sleeve 144 to move member 138 rearwardly so that compressed air can pass from a pressurized head 142 along bore 168 in member 138 to move a screw along delivery tube 140 to the retaining seat opening 38. Movement of block 156 is limited by pin 162. As chuck assembly is moved back forward tie bar 158 moves block 156 which in turn moves member 138 via rod 152. Movement of member 138 forwardly causes leg 171 to eject a screw from the magazine into the delivery tube. The air feed of the screw along the delivery tube is only necessary if the tool is to work beneath a workpiece. Torque limiting device 48 has a driving member 176 driving a driven member 178 via a clutch member 186 wherein balls 194 move out of engagement with recesses 192 when the torque applied overcomes the loading of spring 200. The spring load is adjustable by nut 202.
