Simpson Collated Trim-Head Screw #7 x 2-1/2 in. #2 Square Sharp Point Type 305 Stainless Gray brings together corrosion resistance, low-profile aesthetics, and auto-feed efficiency for wood-to-wood fastening in residential, commercial, and industrial decking projects. Designed specifically for use with the Simpson Strong-Tie Quik Drive auto-feed screw driving system, these gray Type 305 stainless steel screws are extensively tested to ensure problem-free performance across deck boards, docks, and boardwalk applications. Available in colors matched to blend with most major PVC and composite decking manufacturers, these fasteners deliver a clean, finished surface with every drive.

Key Features

• Trim-style head - sits low and inconspicuously on the decking surface, delivering a clean, finished look that keeps the focus on the deck, not the fasteners
• Type 305 stainless steel material and finish - provides high-level corrosion resistance for lasting durability in outdoor, marine, and high-exposure environments
• Patented curved collation strips - hold screws up and away from the work surface, making it easier to move and reposition the Quik Drive tool for a smoother, faster workflow
• Sharp point - pierces wood quickly and accurately, reducing drive time and minimizing the risk of deflection during installation
• Box threads - designed to grip wood-to-wood connections firmly, improving pull-through resistance in structural decking assemblies
• #2 square drive - resists cam-out better than Phillips-style drives, giving the installer more control and reducing stripped heads during high-volume fastening
• Driver bit included in each box - gets you driving immediately without a separate accessory purchase; replacement bit available under model BIT2S
• Gray color option - blends with most major PVC and composite decking products, keeping screw heads visually consistent with the deck surface

Why This Product

• Purpose-built for Quik Drive compatibility - these screws are specifically engineered for use with Simpson Strong-Tie Quik Drive attachments, ensuring consistent, problem-free system performance rather than the fitment uncertainty of generic collated screws
• Aesthetics meet function - the trim-style head and gray finish work together to produce a surface that looks intentional and polished, making these a practical choice for visible deck boards, docks, and boardwalks where appearance matters
• Corrosion resistance you can count on outdoors - Type 305 stainless steel construction stands up to the moisture and weathering conditions common in outdoor decking and waterfront installations, reducing the risk of rust staining or fastener failure over time
• Designed to speed up installation - the curved collation design, sharp point, and auto-feed compatibility combine to reduce handling time, reloading interruptions, and manual pre-drilling, keeping large decking projects moving efficiently
