A driver attachment (12) for a collated screwstrip (13) carrying screws (16) in which a slide body (20) is slidable in a housing (18) parallel a longitudinal axis (52) about which a drive shaft (34) is rotatable. The slide body (20) receives a screwstrip (13) such that a screw feed activation mechanism coupled between the housing (18) and the slide body (20) advances successive screws (16) into a position to be driven by the drive shaft (34) with relative sliding of the slide body (20) relative the housing (18) between an extended and a retracted position. A latch system is provided to latch the slide body (20) to the housing (18) against extension towards the extended position beyond an extension limit position. With the slide body (20) and housing (18) latched together, the drive attachment (12) may be used to drive or withdraw separate screw (16) independently of the screwstrip, with or without the screwstrip (13) engaged in the slide body (20).
