Round Head Machine Screw Toggle Bolts (5/16" x 4") - 25 pc

• Heavy-duty hollow wall anchoring strength — expanding toggle mechanism creates a secure grip behind the wall surface, ideal for mounting shelves, mirrors, fixtures, and wall décor on drywall, plaster, tile, and other hollow materials.
• Spring-action wings for maximum holding power — spring-loaded wings automatically expand once inserted through the wall, distributing weight evenly and preventing pull-through.
• Durable steel construction with corrosion-resistant zinc finish — zinc plated to help resist rust and corrosion in interior environments.
• Versatile for drywall, plaster, tile, and hollow block installation — suitable for shelving brackets, curtain rods, wall-mounted cabinets, lighting fixtures, bathroom accessories, picture frames, and more.
• 25 pieces per retail package.
