#12 x 4" 305 Grade Stainless Steel Construction Screws

305 stainless steel construction screws for structural timber work - joists, beams, substructures, fence posts and deck subframes. At #12 gauge and 4″ long this is the heaviest screw in the Eagle Claw stainless range, sized for the connections that carry the load.

305 stainless resists rust and corrosion, so the frame under your deck will not stain the boards above it or need pulling apart in a few years the way coated and galvanised screws do.

Note: Pre-drilling recommended for dense hardwoods to prevent splitting and ensure optimal holding.

Key Features

• 305 grade stainless steel resists rust, corrosion and staining.
• Star drive (Torx) head prevents cam-out and extends driver life.
• #12 x 4″ is sized for joists, beams, substructures, fence posts and deck subframes.
• Works in both hardwoods and softwoods including cedar, redwood and pressure-treated timber.
• Structural holding power without the corrosion risk of coated or galvanised alternatives.

Step up to 316 marine grade for salt spray and coastal air, tidal or brackish water, pool and spa decks where chlorine is in play, or anything sitting permanently in or over water. For everything else - rain, snow, lakes, rivers and fresh water - 305 is the right grade and costs less.
