Hillman Walldog 20 Pieces

All-steel 1-piece screw anchor. High-profile threads for easy fastening into drywall and masonry based materials. The deep cutting, corkscrew-like threads provide for smooth entry and a powerful hold. Thread design prevents spinning and stripping. When removed, the Walldog leaves a much smaller hole than toggles or other systems. Self-drills through drywall into wood or metal studs. Fastening into concrete, hollow or grout filled block, brick, and plaster requires a pre-drilled 3/16" hole. Walldog anchors are ideal for light to medium-duty anchoring. Typical applications include lightweight fixtures, drapery supports, as well as electrical, telephone, and cable accessories. Available in pan head Phillips (PHP) or oval head Phillips (OHP). 3 colors: Chrome, white, and brass.
