4-piece set of ribbed plastic drywall anchors with flat head self-tapping screws

All are rustproof, corrosion-resistant, and high-quality. These plastic anchors are designed for light-duty anchoring applications and provide extra support for the office or workspace. Drill a hole (depth and diameter to match the anchor) with a power drill, then gently insert the anchor into the hole. They can be used in concrete, blocks, brick, and wall panels. Great value and a handy tool to have on hand for home projects.
