The Simpson CBSDQ106S #8 x 1-1/16 in. Collated Sheathing-to-CFS Screw from Simpson is purpose-built to securely fasten sheathing materials to cold-formed steel (CFS) framing with speed and precision. Its self-drilling point drives into materials easily, while the ribbed flat head with nibs countersinks flush to the surface for a clean, professional finish. Curved-collated for compatibility with the Simpson Quik Drive auto-feed screw driving system, this fastener is engineered to maximize installation efficiency and reduce physical strain on jobs requiring a high volume of fasteners driven in rapid succession. Quik Guard coating delivers corrosion resistance equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, making it a dependable choice for pressure-treated lumber assemblies and demanding CFS applications.

Key Features

• Ribbed flat head with nibs - countersinks flush to the work surface automatically, eliminating extra finishing steps and producing a smooth, consistent result
• #2 undersized square drive - fits snugly to reduce cam-out and keep the bit engaged, improving accuracy and reducing stripped fasteners during high-volume installation
• Drill point with wings - self-drilling tip penetrates cold-formed steel without pre-drilling, while the wings prevent the sheathing from jacking up away from the framing for a tight, secure connection
• Curved collation - designed specifically for use with the Simpson Quik Drive PRO200SG2 auto-feed screw driving system, enabling continuous, ergonomic fastening without bending or manually feeding individual screws
• Quik Guard coating - provides corrosion resistance equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, making these screws suitable for use in pressure-treated lumber assemblies
• Code-compliant for structural applications - CBSDQ screws may be used as prescribed by the codes for shearwalls and diaphragms as described in AISI S240, S400, and S213, giving builders and inspectors confidence in every fastened connection
• Driver bit included - each box ships with a BIT2SU driver bit so installation can begin immediately, with a replacement bit available under the same part number

Why This Product

• Built for high-volume CFS framing jobs - the curved-collated format pairs directly with the Simpson Quik Drive auto-feed system, letting crews drive fasteners in rapid succession without stopping to reload, dramatically cutting labor time on sheathing installation
• Structural confidence backed by code recognition - these screws are approved for use in shearwall and diaphragm construction under AISI S240, S400, and S213, so contractors can specify them with confidence on engineered and inspected projects
• Corrosion protection where it counts - the Quik Guard coating meets the equivalent of hot-dip galvanization (ASTM A153, Class D) in some exposures, making this fastener a reliable choice for assemblies involving pressure-treated lumber where corrosion resistance is critical
• Designed to eliminate common installation problems - the drill point with wings prevents sheathing from jacking during driving, the ribbed flat head countersinks cleanly without over-driving, and the undersized square drive reduces cam-out, combining to produce consistent, professional results across every fastener in the package

Frequently Asked Questions

What tool is required to install the CBSDQ106S screws?

The CBSDQ106S screws install with the Simpson Strong-Tie Quik Drive PRO200SG2 auto-feed screw driving systems and attachments. The curved collation type is specifically designed for compatibility with this system.

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.

Are CBSDQ106S screws code-compliant for shearwall and diaphragm applications?

Yes. CBSDQ screws may be used as prescribed by the codes for shearwalls and diaphragms as described in AISI S240, S400, and S213.

What prevents the CBSDQ106S screw from jacking materials during installation?

The #2 drill point with wings is specifically designed to prevent jacking, ensuring that the sheathing material stays firmly in contact with the cold-formed steel framing as the screw is driven.
