Abstract
A screw package comprising a carrier strip through which the screws extend transversely with the essentially flat under surface of the screw heads resting against the upper surface of the strip. The strip has holes the diameter of which is closely related to the shank diameter of the screws. Around each hole there extend arcuate slots, between the ends of which comparatively weak webs have been left, or deep weakening lines, in such a manner that, as a screw is driven in, a washer consisting of the carrier strip material will be separated from the carrier strip to be clamped between the under surface of the screw head and the work piece wherein the screw is applied.
