These Original Einhell screw strips are an accessory for the Einhell magazine attachment, which is used in conjunction with a drywall screwdriver. The set includes 20 screw strips each holding 50 collated drywall screws, i.e. a total of 1000 screws. The combination of the magazine attachment and screw strips converts the drywall screwdriver into a magazine screwdriver capable of fastening many drywall screws in quick succession. The screws contained in the set are 3.5 mm in diameter, 35 mm long, and have PH2 heads. The fine thread means the screws are suitable for fastening plasterboard to metal substructures.
