#10 x 3-1/2" 305 Grade Stainless Steel Wood Screws

305 stainless steel wood screws for exterior joinery that stays outside - decking, fencing, joists and structural timber. They hold tight in both hardwoods and softwoods and resist the rust and corrosion that stain a finished job.

At 3-1/2″ this is the length for deck joists, thicker dimensional lumber and structural connections where a shorter screw will not reach.

Note: Pre-drilling recommended for dense woods to avoid splitting.

Key Features

• 305 stainless steel resists rust and won’t stain your timber.
• Torx head prevents slipping and makes driving smooth.
• Strong enough for deck joists, fencing and structural connections.
• Works in all hardwoods and softwoods, including cedar, redwood and pressure-treated timber.

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.
