  • Patent number: 5622024
    Abstract: Collated drywall screws are provided for securing drywall to framing members. A collated screw has screws connected to each other by a holding strip. Each screw is received in a frangible sleeve about its threaded shank such that a screw on being screwed into a workplace is separated from the strip by the head of the screw passing through the sleeve breaking the sleeve. The improvement arises in having the head of the screw spaced from the frangible strip by a distance greater than the thickness of the drywall such that a screw is screwed through the drywall in at least partially into the frame support prior to the head of the screw engaging the frangible strip. The increased engagement with the frame member prevents the screw from stripping in the drywall and drawing drywall powder which may clog the power driver after repeated use. The invention provides drywall screws and a method of driving them which reduces the forces a user must manually apply to a power driver.
