Simpson Strong-Tie CBSDQ138S CBSDQ Sheathing-to-CFS Screw (Collated) - #10 x 1-3/8 in. #2 Square Undersized (1500-Qty) is a professional-grade collated fastener engineered by Simpson Strong-Tie to securely attach various sheathing materials to cold-formed steel (CFS) framing. Its self-drilling point drives into materials easily while the ribbed flat head with nibs countersinks flush to the surface for a smooth, clean finish. Collated in a curved strip for compatibility with the Quik Drive auto-feed screw driving system, this screw is the ideal solution for improving speed, efficiency, and ergonomics on jobs requiring multiple fasteners driven in succession - with 1,500 screws per package to keep large projects moving.

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.
