The Simpson Strong-Tie CBSDQ Sheathing-to-CFS Screw (Collated) #10 x 1-3/8 in. is a professional-grade collated fastener engineered to securely attach various sheathing materials to cold-formed steel (CFS) framing. The self-drilling point with wings drives into materials easily while preventing jacking, and the ribbed flat head with nibs countersinks flush to the surface for a smooth, clean finish. Curved-collated for seamless compatibility with the Quik Drive auto-feed screw driving system, this screw delivers the speed, efficiency, and ergonomic advantage that high-volume CFS framing and sheathing applications demand - and each box includes a driver bit so crews can get to work right away.

Key Features

• Ribbed flat head with nibs for easy countersinking - seats flush to the sheathing surface automatically, eliminating extra finishing steps and producing a clean result every time.
• #2 undersized square drive - delivers positive bit engagement and reduces cam-out, keeping the driving process consistent and reducing driver wear over long runs.
• #2 drill point with wings - the self-drilling tip penetrates CFS framing quickly while the wings prevent jacking, ensuring the screw pulls sheathing tight against the steel without lifting.
• Curved collation strip - engineered specifically for use with the Simpson Strong-Tie Quik Drive PRO200SG2 auto-feed screw driving systems and attachments, maximizing throughput and reducing installer fatigue on repetitive fastening tasks.
• Quik Guard coating - suitable for use in pressure-treated lumber and provides a level of corrosion resistance equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, supporting long-term performance in demanding jobsite conditions.
• Code-recognized for shearwall and diaphragm applications - CBSDQ screws may be used as prescribed by the codes for shearwalls and diaphragms as described in AISI S240, S400 and S213, giving engineers and inspectors the documentation they need.
• Driver bit BIT2SU included in each box - crews are ready to install immediately without sourcing a separate bit; replacement bits are available under model BIT2SU.
• 1,500 screws per package - high-count packaging keeps large cold-formed steel framing and sheathing projects moving with fewer interruptions to restock fasteners.

Why This Product

• Built for high-volume CFS sheathing work - the curved-collated format paired with Quik Drive auto-feed compatibility means installers drive significantly more fasteners per hour compared to hand-loading individual screws, directly cutting labor time on large shearwall and diaphragm assemblies.
• Wings that do the work for you - the drill point with wings prevents jacking during installation, so sheathing panels seat properly against the steel framing without the need for repeated repositioning or re-driving.
• Corrosion protection ready for tough exposures - the Quik Guard coating meets the corrosion resistance equivalent of hot-dip galvanization (ASTM A153, Class D) in some exposures, making these screws a dependable choice where moisture, pressure-treated lumber, or harsh jobsite conditions are a concern.
• Code-listed for structural applications - recognized for use in shearwalls and diaphragms per AISI S240, S400 and S213, these screws support engineered CFS assemblies and simplify approval on code-inspected projects.

Frequently Asked Questions

What tool system is compatible with the CBSDQ138S collated screw?

The CBSDQ138S is designed for use with the Simpson Strong-Tie Quik Drive PRO200SG2 auto-feed screw driving systems and attachments. Its curved collation strip is engineered specifically for this system to maximize speed, efficiency, and ergonomics when driving large quantities of fasteners in succession.

What corrosion resistance does the Quik Guard coating provide?

The Quik Guard coating is suitable for use in pressure-treated lumber and provides a level of corrosion resistance that is equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, making it a durable choice for demanding jobsite conditions.

Are CBSDQ138S screws code-compliant for shearwalls and diaphragms?

Yes. CBSDQ screws may be used as prescribed by the codes for shearwalls and diaphragms as described in AISI S240, S400 and S213, providing confidence in structural applications involving cold-formed steel framing.

What does the #2 drill point with wings do, and is a driver bit included?

The #2 drill point with wings prevents jacking - keeping the sheathing material firmly seated against the CFS framing as the screw penetrates - resulting in a tighter, more consistent connection. A driver bit (BIT2SU) is included in each box; the replacement bit model is also BIT2SU.
