#10 x 3 in 304 Grade Stainless Steel Deck Screws 100 Pack - Star Drive

Our review of these #10 x 3 in 304 grade stainless steel deck screws finds them best suited to homeowners, contractors, and DIYers who need reliable, long-lasting fasteners for exterior woodwork. The single biggest reason to buy is simple: the Type 304 stainless construction resists corrosion in coastal and high-moisture environments, so timber stays clean without rust streaks. Included star Torx driver bit and burnished finish make installation neater, while the hardware delivers consistent holding power for decking, fencing, and framing when used with pilot holes.

Key Features

• 304 Grade Stainless Steel: Provides high corrosion resistance so fasteners last much longer than coated alternatives in wet or coastal locations.
• Star Torx Drive: Reduces cam-out and stripping, making installation smoother and preserving the screw head during repeated drives.
• Type 17 Point: Sharp point for easier penetration into hardwoods and treated lumber when used with pilot holes for cleaner starts.
• Versatile for Wood Types: Suitable for hardwoods, softwoods, redwood and cedar, ensuring consistent performance across common exterior timber projects.
• Burnished Finish and Nibs: Clean shiny look with under-head nibs that help seat the screw flush for a polished appearance.

Who It's For

These deck screws are ideal for builders and homeowners working on decks, fences, jetties, balustrades, and walkways, especially where salt air, rivers, or estuaries expose fasteners to moisture. If you need long-term appearance and structural reliability on exterior wood, the 304 stainless alloy is a practical upgrade over plated or coated screws.

Those who should look elsewhere include people who require self-drilling fasteners for metal-to-wood or heavy engineered assemblies, as these screws have a Type 17 point and are intended to be used with pilot holes rather than as self-drilling screws.

Pros & Cons

Pros

• Excellent corrosion resistance for coastal and wet environments thanks to 304 stainless construction.
• Star Torx drive reduces cam-out and makes installation faster and less frustrating.
• Works well across hardwoods, softwoods, and treated lumber for general exterior construction.

Cons

• Not self-drilling; pilot holes are recommended, which adds a step during installation.
