Product Description
The Simpson Strong-Drive PPHD Sheathing-to-CFS Screw - #10 x 1-3/4 in., T25 6-Lobe, Quik Guard Coating (4,000-Quantity) is a precision-engineered fastener built to drive through sheathing materials and into cold-formed steel (CFS) framing with consistent, reliable performance across residential, agricultural, and commercial construction. Its buttressed fine-thread design and extended #5 pilot point work together to deliver secure engagement in CFS applications, while the Quik Guard coating provides protection suited for dry service and low-corrosion environments. Available collated for use in Quik Drive auto-feed screw driving systems or in bulk for hand drive applications, this screw is built to keep production moving on demanding cold-formed steel framing projects.
Key Features
- Larger #5 pilot point with longer flute - enables clean, accurate penetration through sheathing and into cold-formed steel without pre-drilling, saving time on the job.
- Buttressed fine-thread design with 16 TPI - maximizes thread engagement in CFS framing for superior holding power and resistance to pull-through.
- T25 6-lobe recess - delivers a more secure, torque-efficient drive with reduced cam-out risk, improving consistency and reducing installer fatigue during high-volume installations.
- Flat head profile with 0.323 in. head diameter - sits flush against sheathing surfaces for a clean, low-profile finish that does not interfere with overlying materials.
- Quik Guard coating - provides corrosion resistance appropriate for dry service, low-corrosion environments and some fire-rated sheathing assemblies.
- Code-recognized for shearwall and diaphragm applications - PPHD screws may be used as prescribed by the codes for shearwalls and diaphragms as described in AISI S240 and AISI S400, supporting compliance on permitted projects.
- Compatible with Quik Drive auto-feed systems and hand drive applications - gives crews the flexibility to use power-feed equipment for high-production work or drive by hand where needed.
Why This Product
- Purpose-built for sheathing-to-CFS connections - unlike general-purpose metal screws, the PPHD is specifically engineered with a long #5 pilot point and buttressed thread geometry to address the unique demands of fastening sheathing materials directly to cold-formed steel framing, reducing the chance of strip-out or incomplete engagement.
- Code compliance built in - acceptance under AISI S240 and AISI S400 for shearwall and diaphragm applications means contractors can specify this screw with confidence on residential and commercial projects where structural code requirements must be met.
- Flexible installation options for real job-site conditions - collated compatibility with Quik Drive auto-feed screw driving systems alongside bulk availability for hand drive use means this fastener adapts to the equipment and workflow already on site, without requiring a dedicated tool setup.
- High-quantity packaging supports large-scale projects - with 4,000 screws per package, crews working on cold-formed steel framing assemblies can maintain consistent supply through extended sheathing runs without frequent restocking interruptions.

Frequently Asked Questions
- What is the maximum steel thickness this screw can fasten through?
- The Simpson Strong-Drive PPHD Sheathing-to-CFS Screw is rated for a maximum thickness of two layers of 12 gauge steel, totaling 0.218 inches combined. It is designed specifically to drive through sheathing materials and into cold-formed steel (CFS) framing using its long #5 pilot point and extended flute.
- Are these screws code-compliant for 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 projects where code compliance is required.
- What drive tool is required, and why is the T25 6-lobe recess beneficial?
- These screws require a T25 6-lobe (Torx-style) driver bit. The 6-lobe recess provides a more secure, torque-efficient drive with reduced cam-out risk compared to standard drive profiles, improving consistency and reducing installer fatigue during high-volume installations. The screws also come collated for use with Quik Drive auto-feed screw driving systems.
- What environments are these screws designed for?
- These screws are designed for use in dry service, low-corrosion environments and select fire-rated sheathing assemblies. The Quik Guard coating provides a protective finish suited to these conditions. They are not intended for high-moisture or highly corrosive environments.
