Your anchor pulls out on the first serious load — the zinc plating failed, the metal corroded, and now you're back on a service call re-drilling and re-anchoring something that should have held the first time. Ancor metal anchors are what pros reach for when the job can't fail. No. 8 x 1-1/4 inch zinc-plated metal anchor kit. The zinc plating provides corrosion resistance in indoor and protected outdoor applications — adequate for bathrooms, basements, and covered porches where moisture exposure is limited. The threaded anchor body drives into a pre-drilled hole and expands as the screw goes in, creating a firm hold in concrete, brick, or block. The 1-1/4 inch depth works for most light-duty to medium-duty anchoring into standard 2-inch concrete block or poured concrete slabs. Includes mat Stocked at Crofton Lumber and Akron Lumber.
