The Simpson #8 x 3/4" Bugle-Head Wood Deck Screw, Square Drive, 305 Stainless Steel is a purpose-built fastener from Simpson designed for fastening all types of wood decking, including cedar, redwood, and preservative-treated wood. Constructed from Type 305 stainless steel, this square-drive bugle-head screw delivers dependable corrosion resistance for outdoor decking applications while providing a clean, flush finish in the decking surface.

Key Features

• Type-17 Point - Enables fast, efficient starts so the screw begins driving quickly without slipping or walking across the wood surface.
• Bugle Head Profile - Countersinks flush with the decking surface for a smooth, finished appearance that requires no additional tools or plugs.
• Coarse Thread Pattern - Draws decking material tightly down to the substrate for a secure, stable connection that resists loosening over time.
• Type 305 Stainless Steel Construction - Provides reliable corrosion resistance suited to most outdoor wood decking environments, helping the fastener hold up through weather exposure.
• #2 Square Drive - Reduces cam-out during installation, giving the installer better torque control and a more consistent drive compared to slotted or Phillips alternatives.
• Driver Bit Included - Allows work to begin immediately without sourcing a separate bit, saving time on the job.
• Predrilling Recommended Near Board Ends - Helps prevent splitting in cedar, redwood, and treated decking material, protecting the integrity of the boards.

Why This Product

• Built for real outdoor decking demands - Type 305 stainless steel construction resists corrosion in standard outdoor conditions, making these screws a dependable choice for cedar, redwood, and preservative-treated wood deck installations.
• Faster, cleaner installation - The combination of a Type-17 point for quick starts and a #2 square drive for reduced cam-out means less effort and fewer stripped fasteners during a full deck project.
• Professional flush finish every time - The bugle head geometry countersinks naturally into the decking surface without over-driving, leaving a smooth result that reflects quality workmanship.
• Ready to use out of the package - A driver bit is included, so contractors and DIYers can move straight from opening the package to driving fasteners without interruption.

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 advantage of the Type-17 point on this screw?

The Type-17 point is designed for fast starts, allowing the screw to begin driving quickly and efficiently without requiring pre-drilling in most decking situations. Predrilling is still recommended near board ends to prevent splitting.

Why is a bugle head used on this deck screw?

The bugle head profile allows the screw to countersink flush with the surface of the decking material, creating a smooth, finished appearance without the need for additional tools or plugs.

Is Type 305 stainless steel appropriate for all outdoor environments?

Type 305 stainless steel offers solid corrosion resistance for most outdoor decking applications. However, for seaside or high-salt environments, Type 316 stainless steel is recommended for superior corrosion resistance.
