Abstract
A fastener and a nosepiece for use in attaching lath to a support. The fastener includes a screw and a spacing element, in which the spacing element is adapted to threadingly penetrate the lath and abut the support. The lath is retained between the spacing element and the head of the screw and is thereby held away from the support in order to allow plaster to properly extrude through openings in the lath. The nosepiece is attachable to a driving tool and has rigid prongs which reach through openings in the lath. Travel of a bit on the driving tool is limited so that automatic disengagement occurs to prevent over-driving of the screw. The prongs ensure that the lath is held a predetermined distance from the support.
