The Simpson #10 x 2-1/2 in. Collated Bugle-Head Wood Screw in Type 316 Stainless Steel is built for professional builders who need a reliable, corrosion-resistant fastener for wood decking to wood applications, including dock and boardwalk construction. Simpson engineered these screws to install easier and perform better, combining a bugle head design for flush countersinking with curved collation optimized for the Simpson Strong-Tie Quik Drive auto-feed screwdriving system. With Type 316 stainless steel construction throughout, these fasteners deliver severe-level corrosion resistance where it matters most - in demanding outdoor and marine environments where moisture and the elements put every fastener to the test.

Key Features

• Type 316 stainless steel material and finish - provides severe-level corrosion resistance, making these screws well-suited for harsh outdoor and marine environments such as docks and boardwalks where fasteners face constant moisture exposure
• Curved collation for the Simpson Strong-Tie Quik Drive auto-feed screwdriving system - keeps screws feeding smoothly and consistently, reducing interruptions and helping crews drive fasteners significantly faster than hand-loading
• Bugle head design - countersinks flush with the wood surface for a clean, professional finish without damaging surrounding deck board fibers
• #3 square drive - provides superior bit engagement compared to Phillips, reducing cam-out and delivering more controlled, consistent drives in production settings
• Coarse threads - bite aggressively into wood for strong, secure holding power in wood-to-wood fastening applications
• Type-17 point - self-drilling tip bores into wood without pre-drilling, saving time on deck and boardwalk installations
• Driver bit included in each box - gets you working immediately out of the box, with replacement bit model BIT3S available separately so you are never caught short on a job
• 1,500-count packaging - supplies enough fasteners to sustain high-volume professional installations without constant restocking interruptions

Why This Product

• Engineered for speed on production decking jobs - curved collation designed specifically for the Simpson Strong-Tie Quik Drive auto-feed screwdriving system means less time loading fasteners and more time driving them, giving professional crews a measurable productivity advantage on wood decking and boardwalk projects
• Built to hold up in the harshest environments - Type 316 stainless steel is the material of choice when fasteners face prolonged exposure to moisture, salt air, and corrosive conditions, making this screw a dependable long-term choice for marine and waterfront applications like docks and boardwalks
• Designed and tested by the brand builders trust - Simpson focuses on quality and performance testing across its fastener line, so the features on this screw - from the self-drilling Type-17 point to the flush-setting bugle head - are there because they make real installation and long-term performance better, not just as a checklist
• Everything needed to start driving is in the box - with a driver bit included and a clearly identified replacement bit model, this package is ready for immediate use on the job site with the compatible Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment

Frequently Asked Questions

What auto-feed screwdriving system are these screws designed for?

These screws are collated specifically for the Simpson Strong-Tie Quik Drive auto-feed screwdriving system, and are compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment. The curved collation keeps screws feeding smoothly and consistently during installation.

Why is Type 316 stainless steel important for these screws?

Type 316 stainless steel provides severe-level corrosion resistance, making these screws well-suited for harsh outdoor and marine environments. This is particularly important for applications such as dock and boardwalk construction, where fasteners are regularly exposed to moisture and other corrosive conditions.

What are the key specifications of these screws?

These are #10 x 2-1/2 in. bugle-head wood screws featuring a #3 square drive, coarse threads, a Type-17 self-drilling point, and a head diameter of 0.333 in. They are curved-collated and designed for wood decking to wood applications. Each box contains 1,500 screws and includes one driver bit; the replacement bit model is BIT3S.

What is the purpose of the bugle head design on these screws?

The bugle head is designed to provide flush countersinking into wood decking surfaces. This allows the screw head to sit level with or just below the surface of the wood without tearing or damaging the surrounding material, resulting in a cleaner, more professional finish.
