Simpson #7 x 2-1/2 in. Collated Trim-Head Screw brings together the speed of auto-feed installation and the refined appearance of a low-profile fastener, making it a practical choice for residential decks, commercial boardwalks, and dock construction where both aesthetics and long-term durability matter. Built from Type 305 stainless steel and finished in Gray 03, these sharp-point, box-thread screws are engineered specifically for use with the Simpson Quik Drive auto-feed system, delivering consistent, reliable results across PVC and composite decking surfaces in high-exposure environments.

Key Features

• Trim-style head (0.246 in. diameter) - sits low and discreet on the decking surface, producing a clean, finished look with minimal visual distraction on composite or PVC boards
• Type 305 stainless steel construction - provides high-level corrosion resistance suited for demanding, moisture-heavy environments like docks, boardwalks, and outdoor decks
• Gray 03 color-matched finish - blends with most major PVC and composite decking manufacturers, helping fasteners disappear into the board surface for a professional appearance
• Curved collation strips - hold screws up and away from the work surface so the tool moves and positions more easily, reducing fatigue and improving pace on large decking projects
• #2 square drive - provides a secure bit-to-screw engagement that reduces cam-out and keeps installation smooth and consistent
• Sharp point with box threads - penetrates wood-to-wood connections cleanly without pre-drilling, speeding up the fastening process on deck boards and framing
• Driver bit included in every box - gets you working immediately, with replacement bit model BIT2S available for ongoing use
• Designed for the Simpson Quik Drive PRO250G2 auto-feed system - the curved collation is specifically engineered for this attachment, ensuring problem-free system performance and consistent screw depth

Why This Product

• Purpose-built for Quik Drive auto-feed installation - the curved collation strips and sharp-point tip are specifically designed to work with the Simpson auto-feed screw driving system, so you get reliable, repeatable results rather than the misfeed issues that can come with screws not matched to the system
• Corrosion resistance where it counts most - Type 305 stainless steel is the material of choice for marine-adjacent and high-humidity applications like docks and boardwalks, giving these fasteners lasting holding power where standard steel would fail over time
• A cleaner deck surface without extra finishing steps - the trim-style head leaves a low-profile impression that blends into composite and PVC decking, reducing the need for plug covers or additional cosmetic work after installation
• Color-matched to most major decking brands - with Gray 03 formulated to coordinate with popular decking manufacturers, these screws integrate visually into the board surface and maintain a polished, professional result across the full deck or boardwalk installation

Frequently Asked Questions

What tool is required to install these collated screws?

These screws are designed to install with the Simpson Strong-Tie Quik Drive PRO250G2 auto-feed screw driving system or attachment. The curved collation strips are specifically engineered to work with this system, holding screws up and away from the work surface to make moving and positioning the tool easier.

Why is Type 305 stainless steel used for these screws?

Type 305 stainless steel provides high-level corrosion resistance, making these screws well suited for marine or high-exposure environments - such as docks and boardwalks - where PVC or composite decking is installed and resistance to moisture and corrosive elements is critical.

Will the Gray 03 color match my decking material?

These screws are available in 13 colors matched to blend with most major PVC and composite decking manufacturers. Gray 03 is specifically formulated to provide a low-profile, finished appearance on compatible decking surfaces, minimizing the visual impact of the fastener head.

Is a driver bit included, and what is the replacement bit model?

Yes, one driver bit is included in each box of 1,000 screws. If a replacement bit is needed, the compatible replacement bit model is BIT2S.
