The present invention relates to automatic fastening devices and, in particular, a fastening device that drives a fastener into a workpiece by effecting multiple blows upon the fastener. More specifically, the invention relates to a fastening device having a feed assembly operatively connected to a nose assembly for mechanically advancing the fastener into a fastener drive channel. Furthermore, the invention relates to a fastening device wherein a fastener drive channel has a guide surface adjacent the aperture of the nose assembly to direct the fastener as it is driven into the workpiece. The invention also relates to a fastening device having a releasable fastener assembly for releasably securing the nose assembly to the housing of the fastening device. The invention also relates to a fastening device having a control assembly for controlling the operation of the fastening device to conserve energy. Finally, the present invention relates to a coil of collated roofing nails wherein each of the nails is coated with a thermoplastic material that serves as a lubricant which facilitates driving of the nails. The coil of collated roofing nails is adapted for use with the fastening device. A fastening device for driving a fastener into a workpiece by effecting multiple blows upon the fastener comprises a housing and a striker assembly movably mounted within the housing. The striker assembly includes a driver assembly adapted to strike the fastener to be driven into the workpiece. A nose assembly is movably mounted on the housing and has a fastener drive track along which the driver assembly and the fastener travel when the fastener is driven into the workpiece. The fastening device has a feed mechanism operatively connected to the nose assembly for mechanically advancing the fastener into the fastener drive track. The fastener drive track has a guide surface adjacent the aperture of the nose assembly to direct the fastener as it is driven into the workpiece. A releasable fastener assembly releasably secures the nose assembly to the housing of the fastening device. A control assembly controls the operation of the fastening device to conserve energy. A coil of collated roofing nails is adapted for use with the fastening device. Each of the nails of the coil of collated roofing nails is coated with a thermoplastic material that serves as a lubricant which facilitates driving of the nails.
