The Simpson Strong-Tie CBSDQ138-5K CBSDQ Sheathing-to-CFS Screws are engineered for high-volume sheathing installations into cold-formed steel (CFS). With optimized drill points and fine threads, they easily pierce steel framing and secure structural sheathing materials without the need for predrilling.

Designed specifically for attaching wood sheathing, gypsum panels, rigid foam insulation, and other sheathing products to steel up to 16 gauge, these screws deliver reliable holding power and meet code requirements with an ICC-ES listing (ESR-4061). The CBSDQ screws are perfect for commercial framing, multi-family construction, and modular builds where speed and consistency matter most.

Key Features:

• Designed for attaching a variety of sheathing materials to cold-formed steel up to 16 gauge
  
• Self-drilling tip reduces the need for predrilling, saving time and labor
• Optimized thread and point geometry for consistent engagement and reduced stripping
• ICC-ES evaluated under ESR-4061 for code-compliant sheathing-to-steel applications

Applications:

• Structural wood sheathing to steel studs
• Gypsum panels and rigid foam to CFS framing
• Floor sheathing over cold-formed steel joists
• Commercial and multi-family construction
• Modular wall and roof panel assembly

Installation Notes:

• Select screw length based on material thickness and code requirements
• Drive screws flush to the sheathing surface without overdriving
• No predrilling required for most applications in 16 gauge or lighter steel
