Simpson #8 x 2" Bugle-Head Wood Deck Screw with #2 Square Drive in 305 Stainless Steel is a corrosion-resistant fastener engineered by Simpson Strong-Tie for reliable, long-lasting performance in exterior wood applications. Designed specifically for fastening deck boards to joists and other wood-to-wood connections, this screw is compatible with cedar, redwood, and preservative-treated lumber - delivering the kind of durable, flush-finished results that help outdoor structures stand up to the elements for years to come.

Key Features

• Type 305 Stainless Steel material - provides strong corrosion resistance for outdoor and moisture-exposed applications, keeping fasteners secure and rust-free over time in exterior wood installations
• Bugle head design (0.340 in. diameter) - allows the screw to countersink flush with the decking surface without tearing the wood fibers, producing a clean, professional finish
• Type-17 cutting point - pierces wood quickly for fast, efficient starts without the need to pre-drill in most field conditions, reducing installation time
• Coarse threads - draw decking boards and substrate tightly together for a firm, stable connection with strong holding power in wood-to-wood fastening
• #2 Square drive - resists cam-out better than Phillips-style drives, giving the installer improved torque control and reducing bit slippage during installation
• #8 screw size at 2" length - sized for effective penetration and holding strength when fastening standard wood decking boards to joists and framing
• Includes a #2 square driver bit - the package comes ready to use right out of the box, saving a separate trip for tooling

Why This Product

• 305 stainless steel construction makes these screws a dependable choice for decking projects exposed to rain, humidity, and outdoor weather conditions - without sacrificing holding strength
• Compatible with cedar, redwood, and preservative-treated woods, this screw is purpose-built for the materials most commonly used in deck board applications, reducing the guesswork in fastener selection
• The bugle head combined with coarse threads means the screw seats flush and grips firmly in a single driven pass - no additional countersinking hardware or pre-drilling needed in most cases
• The Type-17 point and square drive combination keeps the installation process efficient and precise, especially when driving multiple screws across a full deck surface

Frequently Asked Questions

Can these screws be used with preservative-treated lumber?

Yes. Simpson Strong-Tie specifically states these exterior wood screws are suitable for fastening all types of wood decking, including preservative-treated woods, as well as cedar and redwood.

What drive tool or bit do I need to install these screws?

These screws use a #2 square drive. A #2 square driver bit is included in the package. If you need a replacement, the compatible bit model is BIT2S-2-R2.

Will the screw head sit flush with the deck surface after installation?

Yes. The bugle head profile is specifically designed to countersink flush into the wood surface without the need for a separate countersink bit, producing a smooth, finished appearance.

What is the difference between Type 305 and Type 316 stainless steel for this type of screw?

Type 305 stainless steel offers solid corrosion resistance for most exterior decking environments. For applications near the ocean or in highly corrosive seaside conditions, Simpson recommends choosing Type 316 stainless steel fasteners for superior corrosion resistance in those more demanding environments.
