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