Hillman Fasteners . 9517

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. 3/16 x 1.25" Finish: Chrome Drill size: 3/16" Min.
