In a screw holder in which bands of synthetic resin are disposed on one side of a series of screws out of alignment with the line connecting the center of each screw to stabilize the feed of the screws by the feed pawl of a screwdriver, the screws are driven in the right position regardless of the presence of the bands. A series of screws having an enlarged head are held between a pair of bands of synthetic resin. While a substantially straight main band having a larger cross-sectional area than a secondary band maintains the strength of the screw holder, a secondary band is allowed to bend according to the profile of the screw held therebetween. The outer surface of the main band is flat, whereas an intermediate part between adjoining screws where the two bands meet is flattened without forming a rib-like projection therein. Each screw is caused to bite in the main band to reduce the thickness of its bitten part. |
