Our 4-pack of wood screws is designed to securely attach 3/8-inch, 1/2-inch, and 3/4-inch flanges to wood shelves or tabletops. Each screw measures 0.75 inches in length and fits 1/4-inch mounting holes. The pack includes four 3/4-inch machined alloy screws with 3/8-inch countersunk heads. These screws are ideal for fastening flanges to wood surfaces but are not intended for mounting flanges directly to walls or drywall.
