The Simpson #10 x 2-1/2 in. Collated Bugle-Head Wood Screw in Type 305 Stainless Steel is a professional-grade fastener built for wood decking to wood applications, including decks, docks, and boardwalks. Engineered by Simpson Strong-Tie with the working builder in mind, this screw combines the speed of curved collation with the durability of stainless steel construction, delivering fast, consistent, and corrosion-resistant fastening on every job. The bugle head geometry countersinks flush into decking surfaces without tearing wood fiber, and the Type-17 point gets each screw started quickly without pre-drilling. Each box contains 1,500 screws and includes a driver bit, making this a ready-to-run solution for high-volume exterior wood fastening.

Key Features

• Curved collation for the Simpson Strong-Tie Quik Drive auto-feed screwdriving system - strips feed seamlessly through the Quik Drive PRO300SG2 system or attachment, allowing rapid, consistent placement that significantly reduces installation time on large deck and boardwalk projects.
• Type 305 stainless steel construction - provides additional corrosion resistance compared to standard steel fasteners, making these screws well suited for exterior applications where moisture and the elements are ongoing concerns.
• Bugle head design - countersinks flush into wood decking surfaces cleanly without tearing or splitting wood fiber, producing a smooth, professional finish on every board.
• Type-17 point - self-drilling tip bores into wood quickly for fast starts, eliminating the need for pre-drilling and keeping the installation process moving without interruption.
• Coarse thread profile - delivers strong holding power throughout the full 2-1/2 in. length of the fastener, ensuring a secure, stable connection in wood-to-wood assemblies.
• #3 square drive - provides positive bit engagement that reduces cam-out during high-speed auto-feed driving, protecting both the screw head and the bit.
• Driver bit included in each box - gets crews up and running immediately; a replacement bit is available under model BIT3S when a spare is needed.
• 1,500-count packaging - supplies enough fasteners to cover substantial deck and dock installations without repeated restocking, supporting uninterrupted workflow on the job site.

Why This Product

• Built for auto-feed speed on exterior wood projects - the curved collation is engineered specifically for the Simpson Strong-Tie Quik Drive system, so contractors fastening deck boards, dock planking, or boardwalk surfaces get consistent, high-speed screw placement without hand-loading individual fasteners.
• Stainless steel durability where it counts most - Type 305 stainless steel construction addresses the core challenge of exterior fastening: long-term exposure to moisture. These screws resist corrosion in the conditions that quickly degrade standard steel fasteners, helping the finished structure hold up over time.
• No pre-drilling required - the Type-17 self-drilling point and coarse thread combination bores cleanly into wood and locks in with strong holding power in a single step, cutting labor time without sacrificing connection integrity.
• A complete, job-ready package - with 1,500 screws and an included #3 square drive bit per box, this product is ready to load and run from the moment it arrives, reducing the small delays that add up over the course of a large decking or dock installation.
