These lead shields are circular, hollow, metal anchors with a slit down each side. When in place, the shield bows at the sides when the screw is installed. The outer surface is ribbed to resist coming out of the drilled hole. They can be used in solid or hollow walls and resist temperature fluctuations well. Use with compatible lag screw or wood screw.
