Simpson #7 x 2-1/2 in. Trim-Head Collated Screws in Type 305 Stainless Steel (Brown 01, 1,000-Pack) are engineered for residential, commercial, and industrial fastening applications where a clean, low-profile finish and high-level corrosion resistance are priorities. Part of the Simpson Quik Drive system, these sharp-point, curved-collation screws are purpose-built for installing PVC and composite deck boards on decks, docks, and boardwalks. The patented curved collation strips hold screws up and away from the work surface, making tool movement and positioning easier during installation. Available in Brown 01 - one of 13 colors matched to blend with most major PVC and composite decking manufacturers - these fasteners are extensively tested to ensure optimum performance in their target applications.

Key Features

• Trim-style head - sits low and unobtrusive on the decking surface, delivering a clean, finished appearance that lets the decking material stay the visual focal point
• Type 305 stainless steel construction - provides high-level corrosion resistance, making these screws well-suited for demanding environments such as docks, boardwalks, and coastal deck installations
• Patented curved collation strips - hold screws up and away from the work surface so the tool moves and positions more freely, reducing fatigue and improving workflow on large decking projects
• Sharp point - enables cleaner, faster penetration into composite and PVC decking materials without the need for pre-drilling in most applications
• Box threads - designed to grip composite and PVC decking materials securely, reducing the risk of fastener back-out over time
• #2 square drive - reduces cam-out compared to Phillips-style drives, giving installers better torque control and a more reliable drive on every screw
• Driver bit included in each box - gets you started immediately; replacement bit model BIT2S is available separately when needed
• Brown 01 color-matched finish - blends with popular PVC and composite decking products from most major manufacturers, keeping fastener heads visually discreet
• Quik Drive system compatibility - specifically engineered for use with the Simpson Strong-Tie Quik Drive PRO250G2 auto-feed screw driving system or a compatible Quik Drive attachment, ensuring problem-free system performance

Why This Product

• Built for high-exposure environments - Type 305 stainless steel corrosion resistance makes these trim-head screws a reliable long-term fastening solution for docks, boardwalks, and outdoor deck boards where moisture exposure is a constant concern
• Faster, easier installation with the Quik Drive system - curved collation and Quik Drive compatibility work together to keep the tool positioned correctly and the installation moving efficiently, reducing installer strain on large decking jobs
• Aesthetics built into the fastener design - the trim-style head combined with the Brown 01 color-matched finish means fasteners blend into the decking surface rather than standing out, preserving the finished look of the project
• A complete, tested system from a single brand - Simpson screws are specifically designed and extensively tested for use with Simpson Quik Drive attachments, so installers get predictable, problem-free performance rather than mixing unmatched components

Frequently Asked Questions

What tool is required to install the DTH212S305BR01 trim-head screws?

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

Why are Type 305 stainless steel screws recommended for dock and boardwalk applications?

Type 305 stainless steel provides high-level corrosion resistance, making these screws well-suited for marine or high-exposure environments where PVC or composite decks are installed, such as docks and boardwalks.

What makes the curved collation strip design beneficial during installation?

The patented curved collation strips hold the screws up and away from the work surface, making moving and positioning the tool easier. The strips are also pointed on the inserted end to simplify loading into the Quik Drive system.

Can the Brown 01 color be matched to specific composite or PVC decking brands?

Yes. The Brown 01 color is one of 13 available colors that are matched to blend with most major PVC and composite decking manufacturers, helping the trim-style head remain less noticeable on the decking surface for a clean, finished look.
