<p>A screw alignmewnt device (10) for assisting engagement of a screw driving tool during a fastening operation with a screw of the type having a shank disposed between a head end and a front end, the screw tool being of the type having a shaft with a gripping formation at one end thereof for engagement with the screw head, the screw alignment device including: a screw guide (12) having a body of generally annular configuration formed from a resilient material and having an internal cavity of generally frusto-conical configuration tapering convergently towards a forward end of the device, said screw guide including therein a slit (14) therethrough wherein the slit provides an overlapping portion of one side of said screw guide with respect to the other side of said screw guide so that when overlapping portions (30, 32) of said screw guide on either side of said slit are moved apart with respect to each other as said screw head passes through said screw guide, said overlapping portions remain in an overlapped condition; a tool ge de spaced rearwardly from the screw guide and aligned generally with the cone axis; and a connectorwhich connects the screw guide to the tool guide; where, in use, a screw is located in the screw guide so as to be aligned generally with the cone axis, the front end of the screw projecting through said forward end and the head of the screw being held by the screw guide, and a tool passing through the tool guide can be engaged with the screw head thereby holding the tool and screw aligned, and by driving the screw forward, the head of the screw will cause the screw guide to flex outwardly to permit the screw to pass through the screw guide.</p> |
