The Simpson #6 x 3/4" Bugle-Head Wood Deck Screw, Square Drive, 305 Stainless Steel is a purpose-built fastener from Simpson designed for reliable wood decking installation across a wide range of materials, including cedar, redwood, and preservative-treated wood. Constructed from Type 305 stainless steel, this square-drive screw combines corrosion resistance with precision-engineered geometry to deliver clean, secure fastening in outdoor deck construction.

Key Features

• Type-17 point - bores into wood fiber quickly for fast, confident starts without slipping or wandering, reducing drive time on the job
• Bugle head design - countersinks flush with the wood surface smoothly, minimizing surface tear-out and leaving a clean, professional finish
• Coarse threads running approximately 2/3 up the shank - pull decking boards tightly and evenly down to the substrate, eliminating gaps and producing a solid, stable deck surface
• Type 305 stainless steel construction - resists corrosion in standard outdoor environments, making these screws well suited for exposed deck applications where moisture and weather are ongoing concerns
• #2 square drive - provides superior bit engagement and reduced cam-out compared to other drive types, giving installers better control and consistent torque transfer
• Predrilling recommended near board ends - helps prevent wood splitting at vulnerable board edges, protecting your decking material and ensuring a clean installation from end to end

Why This Product

• Engineered specifically for wood deck fastening - every design element, from the bugle head to the partial-shank thread pattern, is optimized for decking applications in cedar, redwood, and preservative-treated lumber, so installers are not working around a general-purpose fastener
• Stainless steel durability without constant upkeep - Type 305 stainless steel holds up against the moisture, humidity, and temperature swings that degrade standard fasteners over time, helping deck installations stay tight and rust-free through years of outdoor exposure
• Reduces cam-out and drive frustration - the #2 square drive interface grips securely, so screws seat fully and consistently without the bit slipping out mid-drive, saving time and reducing wasted fasteners
• Driver bit included - the package comes ready to use straight out of the box, so there is no need to source a separate square-drive bit before starting a project

Frequently Asked Questions

What type of wood is this screw compatible with?

This screw is suitable for fastening all types of wood decking, including cedar, redwood, and preservative-treated woods.

What is the purpose of the Type-17 point on this screw?

The Type-17 point is designed for fast starts, making it easier to drive the screw into wood decking without pre-drilling in most field conditions. However, predrilling is recommended near board ends to prevent splitting.

Why are the coarse threads only 2/3 up the shank?

The coarse threads running approximately 2/3 up the shank are specifically designed to draw the decking and other material tightly to the substrate, ensuring a secure and flush installation.

Is this screw suitable for seaside or highly corrosive environments?

While Type 305 stainless steel offers good corrosion resistance for standard outdoor decking applications, Type 316 stainless steel is recommended for seaside applications and superior corrosion resistance in more demanding environments.
