Simpson #8 x 2" Bugle-Head Wood Deck Screw with #2 Square Drive in Type 316 Stainless Steel is engineered by Simpson Strong-Tie for durable, corrosion-resistant fastening in outdoor decking applications. Designed to fasten all types of wood decking - including cedar, redwood, and preservative-treated lumber - this screw delivers a flush, clean finish and dependable holding strength in even the most demanding exterior environments. The Type 316 stainless steel material provides superior resistance to moisture, salt exposure, and harsh outdoor conditions, making it an ideal choice for seaside decks and high-humidity installations where long-term performance is essential.

Key Features

• Type 316 Stainless Steel material - offers superior corrosion resistance compared to standard stainless grades, making it the right choice for coastal, seaside, and wet outdoor environments where fasteners face constant moisture and salt exposure.
• Bugle head design with 0.340" head diameter - allows for smooth, flush countersinking into wood decking surfaces without tearing or damaging the wood fibers, resulting in a clean, professional finish.
• #2 Square drive - provides positive bit engagement and reduces cam-out during installation, improving drive control and reducing installer fatigue on large decking projects.
• Type-17 cutting point - enables fast, clean starts in wood without pre-drilling in most applications, speeding up installation and reducing the chance of surface splitting.
• Coarse threads - draw decking boards tightly to the substrate for a secure, tight connection that minimizes gaps and movement over time.
• 2" length in #8 screw size - provides an appropriate depth of penetration for standard wood decking installations, balancing holding power with practical fastening depth.
• Compatible with cedar, redwood, and preservative-treated woods - ensures the screw is suited to the most commonly used deck board materials without risk of corrosion-related staining or fastener degradation.
• Driver bit included - allows you to start fastening right away without needing to source a separate #2 square bit, adding convenience on the job site.

Why This Product

• Built for demanding outdoor and coastal applications - Type 316 stainless steel is specifically recognized for its performance in saltwater and chemically aggressive environments, making this screw a reliable long-term fastener for decks near the ocean or in humid climates.
• Engineered for a clean deck surface - the bugle head geometry is purpose-designed for wood decking, countersinking flush without surface tear-out, so your finished deck looks as clean as it performs.
• Faster, more controlled installation - the combination of the Type-17 self-starting point and the #2 square drive reduces the effort and time needed to drive each screw, making this a practical choice for larger deck projects.
• Trusted fastener brand for wood-to-wood decking - Simpson Strong-Tie formulates these exterior screws specifically to address the demands of outside living spaces, with thread geometry and material selection matched to real-world decking conditions.

Frequently Asked Questions

Why should I choose Type 316 stainless steel screws over standard stainless steel for my deck?

Type 316 stainless steel contains added molybdenum, which significantly improves resistance to chlorides, saltwater, and corrosive chemicals compared to standard 304 stainless. This makes it the preferred choice for decks in coastal or seaside environments, as well as anywhere preservative-treated lumber is used, where standard fasteners may corrode prematurely.

Will this screw work with pressure-treated, cedar, or redwood deck boards?

Yes. These screws are specifically designed for use with all common wood decking materials, including cedar, redwood, and preservative-treated woods. The Type 316 stainless steel construction ensures compatibility without the risk of corrosion-related staining that can occur with lower-grade fasteners when used with treated lumber.

Do I need to pre-drill before driving these screws?

In most standard decking applications, the Type-17 self-starting point eliminates the need for pre-drilling by cutting cleanly into the wood for fast starts. However, pre-drilling is recommended near board ends to help prevent splitting, particularly with harder wood species or near the edges of deck boards.

What drive bit do I need for these screws, and is one included?

These screws use a #2 square drive, and a #2 square driver bit is included with each package so you can begin work immediately. If you need a replacement bit, the compatible model is BIT2S-2-R2.
