Product Description
Simpson Strong-Tie CBSDQ158S CBSDQ Sheathing-to-CFS Screw (Collated) - #8 x 1-5/8 in., #2 Square Undersized, 1500-Pack is engineered by Simpson Strong-Tie to securely fasten 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 surfaces for a smooth, professional finish.

Frequently Asked Questions
- What auto-feed screw driving systems are compatible with the CBSDQ158S?
- The CBSDQ158S collated screws install with the Simpson Strong-Tie Quik Drive PRO200SG2 or PRO250G2 auto-feed screw driving systems and their compatible attachments. This system improves speed, efficiency, and ergonomics when driving multiple fasteners in succession.
- What type of 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 appropriate for demanding outdoor and structural applications.
- Are CBSDQ158S screws approved for use in 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, making them a code-compliant choice for cold-formed-steel framing assemblies.
- What is the purpose of the drill point with wings on the CBSDQ158S?
- The #2 drill point with wings on the CBSDQ158S is specifically designed to prevent jacking - a condition where the screw lifts the sheathing material away from the substrate during driving. This ensures a tight, flush connection between the sheathing and the cold-formed-steel framing.
