Hillman Steel Zinc-Plated Plaster Washer

Hillman Plaster Washers provide a firm grip without damaging the plaster and wallboard behind it. This 1-inch diameter countersunk washer is made of steel, and the zinc finish offers moderate corrosion resistance. A drywall screw is hammered into the wood lath behind the plaster after passing through the washer. The Hillman washers firmly anchor the plaster against the lath, preventing cracks and holding a sagging ceiling in place.
