The OMG INC FMGD312-75 is a 75-pack of number 9 diameter, 3.5-inch gold-coated exterior deck screws designed for use with pressure-treated lumber and other corrosive-environment wood types. Each screw features a Pozisquare drive pattern, which combines a Pozidriv and square recess for improved bit engagement and reduced cam-out during installation. The gold coating provides corrosion resistance compatible with ACQ treated lumber, Copper Azole, Cedar, and Redwood. A free Pozisquare driver bit is included in the clear plastic storage bucket. Licensed contractors, deck builders, and experienced DIYers working with exterior wood assemblies will find these suitable for structural and finish fastening tasks.
These deck screws are intended for exterior applications where treated or naturally rot-resistant lumber is used, including residential and light commercial deck construction. The gold color is formulated to match the appearance of common pressure-treated lumber, providing a cleaner finished look on exposed fastener heads. The ACQ and Copper Azole coating compatibility makes them appropriate for modern preservative-treated wood, which can accelerate corrosion in standard fasteners. The 75-count pack with included driver bit supports a full small-to-mid deck section repair or new build phase without requiring a separate bit purchase.
Coated for use with ACQ treated lumber, Copper Azole treated wood, Cedar, and Redwood. Designed as an exterior-rated deck fastener compatible with pressure-treated wood assemblies where standard zinc-plated screws are not recommended.
Deck screws of this type are typically installed by carpenters, deck builders, or licensed general contractors following local building codes. Power down any adjacent electrical or disconnect any relevant services before working in confined deck framing areas. Use the included Pozisquare driver bit with a variable-speed drill or impact driver set to an appropriate clutch setting to avoid overdriving and splitting lumber. Pre-drilling pilot holes is recommended near board ends to prevent splitting, especially in Cedar and Redwood.
