The SD-M 1 screw magazine improves the workflow of interior finishing professionals. Instead of a conventional, flexible magazine strip, a rigid strip is used. This new concept eliminates the need for a depth gauge at the screw exit, making it much easier to use screws of different lengths. The individual screws are transported smoothly without any resistance, thus preventing the magazine from jamming. Moreover, the screw magazine is compatible with all drywall screwdrivers by this manufacturer.
