The Simpson Strong-Drive PPHD Sheathing-to-CFS Screw is a collated fastener engineered to drive through sheathing materials and directly into cold-formed steel (CFS) framing - no pre-drilling required. Built around a larger #5 pilot point with a longer flute, this #10 x 1-3/4 in. flat-head screw delivers clean, accurate starts and reliable penetration in CFS applications across residential, agricultural, and commercial projects. Fine threads, a T25 6-lobe recess, and yellow-zinc coating round out a fastener designed for dry service and low-corrosion environments, including some fire-rated sheathing assemblies.

Key Features

• Larger #5 pilot point with longer flute - drives clean through sheathing and into cold-formed steel without pre-drilling, saving time and reducing prep steps on the job.
• Fine threads at 16 TPI - engineered for consistent, secure engagement in cold-formed steel for reliable holding strength in structural sheathing connections.
• T25 6-lobe recess - provides a more secure bit engagement that resists cam-out, keeping your drive accurate and reducing stripped fasteners.
• Collated format compatible with Quik Drive PRO300SG2, PRO250G2, and PRO200SG2 auto-feed systems - lets crews install sheathing faster with an auto-feed screw driving system rather than hand-driving one screw at a time.
• Approved for shearwall and diaphragm applications per AISI S240 and AISI S400 - gives builders and inspectors confidence that these screws meet code requirements for structurally critical assemblies.
• Yellow-zinc coating - suited for dry service and low-corrosion environments, including some fire-rated sheathing applications, so the fastener holds up in the conditions it was selected for.
• Two T25 6-lobe driver bits included - means crews can get started immediately, with replacement bits available under model QRTX25-1.5 when needed.

Why This Product

• No pre-drilling needed in CFS framing - the purpose-built #5 pilot point with extended flute penetrates cold-formed steel cleanly on contact, cutting installation time and eliminating an extra step that slows sheathing crews down.
• Code-recognized for structural applications - PPHD screws are accepted for use in shearwall and diaphragm assemblies under AISI S240 and AISI S400, making them a dependable choice when project documentation and inspection sign-off matter.
• Built for auto-feed productivity - collated and compatible with Simpson Strong-Tie Quik Drive auto-feed screw driving systems, these CFS sheathing screws are set up for high-volume installation without sacrificing drive quality or fastener consistency.
• Engineered specifically for sheathing-to-CFS connections - the combination of fine threads, flat-head profile, and pilot-point geometry is purpose-matched to wood-to-steel sheathing work, so contractors are not adapting a general-purpose fastener to a specialized task.

Frequently Asked Questions

What 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. Two T25 6-lobe driver bits are included in the package, and replacement bits are available under model QRTX25-1.5.

Do these screws require pre-drilling when fastening sheathing to cold-formed steel?

No pre-drilling is required. The PPHD screw features a larger #5 pilot point with a longer flute that is specifically engineered to drive clean, accurate starts directly through sheathing materials and into cold-formed steel (CFS) framing without any pre-drilling.

Are these screws suitable for code-required 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 appropriate for residential, agricultural, and commercial projects where code compliance is required.

What environments are these screws designed for, and what is their coating?

These screws feature a yellow-zinc coating and are designed for use in dry service, low-corrosion environments. They are also suitable for use in some fire-rated sheathing applications. They are not intended for high-moisture or highly corrosive environments.
