Product Description
The Simpson Strong-Drive PPHD Sheathing-to-CFS Screw is purpose-built for fastening wood structural panel sheathing to cold-formed steel (CFS) framing in residential, agricultural, and commercial construction. Engineered with a long #5 pilot point with an extended flute and a buttress thread design, this #8 x 1-15/16 in. flat-head screw drives efficiently through sheathing materials and into metal substrates with minimal resistance. The T25 6-lobe recess reduces cam-out for more reliable engagement, and the collated format makes it fully compatible with Simpson Quik Drive auto-feed screw driving systems for high-productivity installations. Two T25 6-lobe driver bits are included, and the yellow-zinc coating provides protection suited for dry service and low-corrosion environments.
Key Features
- Larger #5 pilot point with longer flute - penetrates sheathing and cold-formed steel faster and with greater precision, reducing installation effort on steel-framing projects.
- Buttress threads and dog-ear point - designed for faster drilling through sheathing and metal, so crews can maintain a consistent pace without pre-drilling.
- T25 6-lobe recess - provides a more secure drive engagement that minimizes cam-out and bit wear, improving control during installation.
- Collated format compatible with Quik Drive PRO300SG2, PRO250G2, and PRO200SG2 - integrates directly with Simpson auto-feed screw driving systems for continuous, hands-free driving that boosts jobsite productivity.
- Code-recognized for shearwalls and diaphragms - may be used as prescribed under AISI S240 and AISI S400, giving contractors a code-compliant fastening solution for structural CFS applications.
- Two T25 6-lobe driver bits included - replacement bit model QRTX25-1.5 keeps your system running without a separate trip to the supply house.
- Yellow-zinc coating - suited for dry service, low-corrosion environments and some fire-rated sheathing assemblies, broadening the range of eligible applications.
Why This Product
- Engineered specifically for sheathing-to-CFS connections - the combination of the #5 pilot point, extended flute, and buttress thread design means this screw handles the distinct challenge of penetrating wood-based sheathing and cold-formed steel in a single step, without the need for a separate drill point or pre-drilled hole.
- Built for auto-feed and hand-drive flexibility - collated for use with the Quik Drive PRO200SG2, PRO250G2, and PRO300SG2 systems yet equally capable in hand-drive applications, this fastener adapts to the tools already on your jobsite.
- Structural code compliance built in - acceptance under AISI S240 and AISI S400 means these screws satisfy code requirements for shearwall and diaphragm assemblies, removing guesswork from the approvals process on residential and commercial steel-framing jobs.
- A complete, ready-to-install package - two T25 6-lobe driver bits ship with every box, so the hardware needed to start driving immediately is already included, reducing setup time on the job.

Frequently Asked Questions
- Which auto-feed screw driving systems are compatible with these collated screws?
- These collated PPHD screws are compatible with the Simpson Strong-Tie Quik Drive PRO200SG2, PRO250G2, and PRO300SG2 auto-feed screw driving systems. They can also be used in hand-drive applications outside of an auto-feed system.
- What type of materials are these screws designed to fasten?
- The Strong-Drive PPHD screw is designed specifically for fastening sheathing materials to cold-formed steel (CFS). The long #5 drill point with extended flute and buttress thread design allow it to penetrate both sheathing and metal substrates efficiently.
- Are these screws approved for use in shearwall and diaphragm applications?
- Yes. PPHD screws may be used as prescribed by the codes for shearwalls and diaphragms as described in AISI S240 and AISI S400, making them suitable for residential, agricultural, and commercial steel-framing projects where code-compliant performance is required.
- What driver bit is required, and are any bits included with this package?
- These screws require a T25 6-lobe driver bit. This 2,000-count package includes two T25 6-lobe driver bits. If replacement bits are needed, the compatible replacement bit model is QRTX25-1.5.
