Abstract:
1. A curved screwstrip comprising in combination a plastic holding strap and a plurality of threaded fasteners; each fastener disposed about an axis and having a head at an upper end, a tip extending from the other lower end and a shank extending from below the head to the tip about the axis, threads about the shank, the holding strap holding the fasteners in a row in spaced side-by-side relation with the axis of the fasteners in a common plane; at least a portion of the holding strap holding the fasteners in a generally curved configuration wherein the heads of the screws lie on a first curve in the common plane and the tips of the screws lie on a second curve in the common plane, wherein at each fastener in the portion a radius of curvature of the first curve is less than a radius of curvature of the second curve, the holding strap comprises an elongate beam member which extends axially relative the fasteners and longitudinally between fasteners, the beam having a height measured parallel the axis of the fasteners between an upper most surface of the beam and a lowermost surface of the beam, a middle of the beam defined as halfway between the uppermost surface and the lowermost surface with a top portion above the middle and a bottom portion below the middle, the beam formed of plastic material of substantially constant density, the top portion of the beam having a top mass, the bottom portion of the beam having a bottom mass, the top mass being greater than the bottom mass.
