The Simpson #10 x 1 1/2 in. Type 410 Stainless Steel Collated Flat Head Wood-to-CFS Screw is purpose-built for fastening wood or wood structural panel sheathing to cold-formed steel framing, with a recommended maximum steel thickness of 3/16 in. Curved collation pairs this screw with the Simpson Strong-Tie Quik Drive PROPP150G2 auto-feed screw driving attachment for fast, consistent placement across high-volume framing and sheathing work. A drill point, nibs under the flat head, and a clear zinc coating over the Type 410 stainless steel base combine to deliver clean installation and lasting corrosion resistance in demanding structural applications.

Key Features

• Flat head with countersinking nibs - The nibs under the flat head allow the screw to seat flush without pre-drilling a countersink, saving time and delivering a clean, professional finish on wood-to-steel connections.
• Drill point - Penetrates cold-formed steel cleanly without a pilot hole, reducing installation steps and keeping work moving on structural sheathing and framing projects.
• Curved collation - Designed for use with the Simpson Strong-Tie Quik Drive PROPP150G2 auto-feed attachment, enabling rapid, consistent driving across large sheathing surfaces and high-count installations.
• #2 square drive - Provides a secure bit-to-screw engagement that reduces cam-out during installation, giving the installer better control and a cleaner drive every time.
• Type 410 stainless steel construction with clear zinc coating - The stainless steel base combined with an added clear zinc coating delivers enhanced corrosion resistance, making these screws well-suited for applications where long-term durability is a priority.
• Bulk pack of 1,000 screws - Reduces the need for frequent restocking on large framing or sheathing jobs, keeping crews productive without interruption.

Why This Product

• Engineered specifically for wood-to-cold-formed-steel connections - Unlike general-purpose fasteners, this screw is designed around the demands of attaching wood or wood structural panel sheathing to CFS framing, including a drill point and geometry matched to steel up to 3/16 in. thick, so the fit is right for the application from the start.
• Auto-feed compatibility cuts installation time significantly - The curved collation works directly with the Simpson Strong-Tie Quik Drive PROPP150G2, allowing crews to drive screws rapidly and consistently without stopping to hand-load each fastener, which makes a measurable difference across large sheathing runs.
• Dual-layer corrosion protection built into every screw - Type 410 stainless steel paired with a clear zinc coating means these fasteners resist corrosion at both the material and coating level, supporting long-term structural integrity in exposed or moisture-prone framing environments.
• Flush-seating flat head eliminates extra prep work - The countersinking nibs under the flat head let the screw pull itself flush with the wood surface during installation, removing the need for a separate countersink step and keeping panel attachment clean and code-ready.
