ABSTRACT:
A screw strip is disclosed in which each screw carries a washer on its screw shank between the tip of the screw and a plastic strip carrying a plurality of screws. A screw driving apparatus, and method of use of the strip are also disclosed. The washers and screw heads are of relatively large diameter and adjacent washers overlap each other. The power tools used to install the screws include indexing means which advance successive screws into driving position, and retract the remaining screw strip rearwardly in order to avoid interference between the driving tool, the driven screw and adjacent washers. This configuration permits application of large head screws such as hexagonal head screws carrying large washers by power tool socket drivers and is particularly useful in sheet metal applications. The invention is applicable to any fastener with a threaded shank including bolts and screws.
