Simpson Collated Trim-Head Screw #7 x 2-1/2 in. #2 Square Sharp Point Type 305 SS Gray 01 is a precision-engineered collated decking fastener from Simpson, purpose-built for wood-to-wood fastening on decks, docks, and boardwalks in residential, commercial, and industrial settings. Made from Type 305 stainless steel for high-level corrosion resistance, these Quik Drive collated screws pair a low-profile trim head with a Gray 01 color matched to blend with most major PVC and composite decking manufacturers - delivering a clean, professional finish that lets the decking take center stage. Each box includes a driver bit, and the patented curved collation strips hold screws up and away from the work surface to make tool positioning and movement easier across the deck.

Key Features

• Trim-style head - sits low and inconspicuous on the decking surface, producing a clean, finished look without bulky screw heads drawing attention
• Gray 01 color-matched finish - blends with most major PVC and composite decking manufacturers so fasteners visually disappear into the board surface
• Type 305 stainless steel material - provides high-level corrosion resistance, making these screws reliable in marine, waterfront, and other high-exposure environments
• Curved collation strips - hold screws up and away from the work surface, making moving and positioning the Quik Drive tool easier and speeding up installation
• #2 square drive - reduces cam-out during driving for more positive bit engagement and consistent results across every fastener
• Sharp point - starts cleanly without pre-drilling, reducing prep time on wood decking and boardwalk projects
• Box threads - designed to pull boards down tight and hold firmly in wood substrates for a secure, lasting connection
• Driver bit included in every box - gets you started immediately with no separate bit purchase required; replacement bit model BIT2S available when needed
• Engineered for the Simpson Quik Drive auto-feed system - specifically designed for use with Quik Drive attachments to ensure problem-free system performance and consistent screw depth

Why This Product

• A color-matched fastener built for composite and PVC decking - the Gray 01 finish is specifically matched to blend with most major PVC and composite decking manufacturers, so screws integrate seamlessly rather than standing out as an eyesore on the finished surface
• Corrosion resistance you can count on near water - Type 305 stainless steel construction makes these trim-head screws a dependable choice for docks, boardwalks, and waterfront decks where long-term durability against the elements is critical
• Designed from the ground up for Quik Drive auto-feed installation - the curved collation, sharp point, and box thread geometry work together with the Simpson Quik Drive system to deliver problem-free, consistent performance rather than the misfires and jams that can come with generic collated screws

Frequently Asked Questions

What tool is required to use these collated screws?

These screws are designed to install with the Simpson Strong-Tie Quik Drive PRO250G2 auto-feed screw driving system or compatible attachment. They are specifically engineered for use with Quik Drive attachments to ensure problem-free system performance.

Why choose Type 305 stainless steel for deck screws?

Type 305 stainless steel provides high-level corrosion resistance, making these screws well-suited for marine and high-exposure environments where PVC or composite decks are installed and where long-term durability against the elements is critical.

How does the trim-head design benefit the finished deck appearance?

The trim-style head is less noticeable on the decking surface compared to standard screw heads, offering a clean, finished look. The Gray 01 color is matched to blend with most major PVC and composite decking manufacturers, helping the fasteners visually disappear into the deck surface.

What is the advantage of curved collation strips on these screws?

The patented curved collation strips hold the screws up and away from the work surface. This design makes moving and repositioning the Quik Drive tool easier during installation, improving workflow efficiency. The screws are also pointed on the inserted end to simplify loading into the system.
