Dottie DDFW103 Screw, #10 3" Square Drive Flat Head Wood Screw

For contractors and installers who mount security and surveillance equipment, the Dottie DDFW103 wood screw gives dependable holding power where it matters most. This #10, 3" square-drive wood screw features an aggressive 13 TPI thread and a countersunk flat head to deliver a flush, professional finish on plywood, lumber and mounting blocks. Constructed from carbon steel, the fastener resists shear and provides long-term support for CCTV brackets, monitoring enclosures and low-voltage wiring assemblies.

The square (Robertson) drive reduces cam-out and speeds repetitive installations with power tools, lowering labor time on large projects. Each pack of 100 fasteners helps standardize hardware on job sites and keeps spare parts on hand for field adjustments. For best results, pre-drill a pilot hole slightly smaller than the screw diameter to prevent splitting in hardwoods and engineered substrates.

Choose the Dottie DDFW103 when you need reliable, flush-mounted wood screws for security, surveillance and general carpentry applications. Add to cart to stock your next installation with dependable, contractor-grade fasteners.
