Simpson Collated Trim-Head Screw #7 x 2-1/2 in. 305 Stainless Sharp Point #2 Sq Drive 1000-Pk by Simpson is a collated decking screw built for marine and high-exposure outdoor environments where PVC or composite decking demands reliable, long-lasting fastening. Type 305 stainless steel construction delivers high-level corrosion resistance against moisture and harsh conditions, while the trim-style head keeps the finished deck surface looking clean and polished. Curved collation makes these screws compatible with the Simpson Strong-Tie Quik Drive auto-feed screw driving system, supporting fast, consistent installation across large decking projects including docks and boardwalks.

Key Features

• Trim-style head - sits lower and less noticeable on the decking surface, delivering a clean, finished appearance that standard screw heads cannot match
• Type 305 stainless steel material and finish - provides high-level corrosion resistance, making these fasteners well suited for marine environments, docks, boardwalks, and other high-exposure outdoor installations
• Curved collation - designed for use with compatible auto-feed screw driving systems, enabling faster and more efficient installation across large deck surfaces
• #2 square drive - reduces bit slippage during driving, promoting consistent, reliable fastening and less wear on the drive recess
• Sharp point - penetrates PVC and composite decking materials quickly and cleanly, eliminating the need for pre-drilling and saving time on the job
• Box threads - engineered to grip decking materials securely, helping hold fastened boards firmly in place over time
• Driver bit included - a #2 square drive bit ships in every box so installation can begin immediately; replacement bit model BIT2S is available separately

Why This Product

• Purpose-built for demanding outdoor environments - Type 305 stainless steel construction holds up against the moisture, salt air, and weathering common in marine settings, docks, and boardwalk applications where fastener corrosion is a serious long-term concern
• Cleaner results on composite and PVC decks - the trim-style head design is specifically suited to the aesthetics of PVC and composite decking, leaving a low-profile, finished look that blends into the surface rather than standing out
• Faster installation with auto-feed compatibility - curved collation designed for the Simpson Strong-Tie Quik Drive PRO250G2 system means less handling per screw and significantly quicker coverage on large decking projects
• No pre-drilling required - the sharp point drives directly into PVC and composite materials, reducing steps in the installation process and helping crews work more efficiently from start to finish
