Simpson #8 x 2" Type 305 Stainless Steel Bugle-Head Wood Screw with T-20 6-Lobe Drive by Simpson Strong-Tie is engineered for fastening all types of wood decking where long-term durability and corrosion resistance are essential. The Type 305 stainless steel construction makes these screws well-suited for use with cedar, redwood, and preservative-treated lumber, delivering lasting holding power even in demanding outdoor environments. The bugle head profile allows for smooth, flush countersinking that leaves a clean, professional finish - ideal for deck boards, wood cladding, and exterior woodworking applications where appearance and performance both matter.

Key Features

• Type 305 Stainless Steel material - provides superior corrosion resistance for use with cedar, redwood, and preservative-treated woods, keeping fasteners looking clean and structurally sound over time in wet and outdoor conditions
• T-20 6-Lobe drive recess - delivers a secure bit engagement that reduces cam-outs during driving, resulting in longer bit life and a cleaner, more controlled installation experience
• Bugle head profile engineered for flush countersinking - seats smoothly into wood surfaces without tearing fibers, yielding a more concealed, professional-looking fastening result
• Type-17 cutting point - designed for fast, self-starting penetration into wood, reducing the need for predrilling in most applications and speeding up installation
• Coarse thread pattern - threads grip firmly along approximately two-thirds of the shank, drawing decking boards and other wood materials tightly down to the framing beneath
• #8 x 2" size (0.340 in. head diameter) - a versatile dimension that suits standard deck board fastening on common framing layouts, balancing holding strength with a low-profile head

Why This Product

• Purpose-built for treated lumber and moisture-prone decking applications - the Type 305 stainless steel finish resists the corrosive chemistry found in preservative-treated wood, cedar, and redwood, preventing the staining and weakening that standard fasteners experience over time outdoors
• The 6-lobe T-20 drive system reduces installer frustration and tool wear - cam-outs are minimized with each drive cycle, which means fewer stripped screw heads and more consistent results across a full deck installation
• The bugle head geometry eliminates the need for a separate countersinking step - the screw seats flush automatically as it drives, creating a smooth surface and a finished look without extra labor
• At approximately 128 screws per pound, this screw offers a reliable count for planning material quantities on decking projects of varying sizes, making it easy to estimate what you need before starting the job

Frequently Asked Questions

What types of wood are these screws compatible with?

These screws are designed to fasten all types of wood decking, including cedar, redwood, and preservative-treated woods. Note that they are intended for non-hardwood applications.

What driver bit does the T-20 6-Lobe drive require?

The T-20 6-lobe drive recess requires a T20 6-lobe driver bit. This drive style is specifically chosen to provide a secure bit engagement that reduces cam-outs and extends bit life compared to standard drive types.

Why is stainless steel recommended for deck screws used with treated lumber?

Preservative-treated lumber contains chemicals that can accelerate corrosion in standard steel fasteners, leading to staining of the wood surface and weakening of the fastener over time. Type 305 stainless steel offers superior corrosion resistance that stands up to the chemistry in treated wood, cedar, and redwood in outdoor environments.

Is predrilling required when using these screws?

The Type-17 cutting point is designed for fast starts and direct penetration into wood without predrilling in most cases. However, predrilling is recommended near board ends to help prevent wood splitting.
