Product Description
The Simpson Strong-Drive PPHD Sheathing-to-CFS Screw (#12 x 1-3/4 in., Collated, 1,000-Pack) is engineered to drive through sheathing materials and into cold-formed steel (CFS) with speed and precision. Its long #5 drill point pierces CFS framing cleanly, while the flat head with underhead nibs countersinks flush for a professional, low-profile finish. Pre-collated for seamless compatibility with the Simpson Strong-Tie Quik Drive PROHSD60 and PROHSD60M auto-feed screw driving systems, these fasteners dramatically increase productivity on residential, agricultural, and commercial framing projects. The Quik Guard coating provides corrosion resistance suited for dry service and low-corrosion environments, including select fire-rated sheathing assemblies. Compliant with AISI S240 and AISI S400 code requirements for shearwalls and diaphragms, the PPHD is a code-ready solution trusted by structural professionals.
Key Features
- Larger #5 Pilot Point with Longer Flute - Penetrates cold-formed steel framing efficiently without pre-drilling, reducing installation time.
- Underhead Nibs for Easy Countersinking - Flat head with integrated nibs seats flush into sheathing for a clean, snag-free surface.
- 6-Lobe (T25) Recess for a More Secure Drive - Reduces cam-out and driver slippage, delivering consistent torque transfer and a more reliable installation.
- Quik Guard Coating - Provides corrosion resistance for dry service, low-corrosion environments, and use with some fire-rated sheathing panels.
- Collated for Auto-Feed Systems - Compatible with the Quik Drive PROHSD60 and PROHSD60M auto-feed screw driving systems for high-speed, high-volume installation.
- Code-Compliant for Shearwalls & Diaphragms - PPHD screws may be used as prescribed by the codes for shearwalls and diaphragms as described in AISI S240 and AISI S400.
- Fine Thread Design (14 TPI) - Optimized thread pitch grips cold-formed steel securely without stripping.
- Driver Bits Included - Two (2) T25 6-lobe driver bits included in every box; replacement bit model: QRTX25-1.5.
- 1,000-Count Pack - High-volume packaging designed for professional, large-scale sheathing applications.

Frequently Asked Questions
- What auto-feed screw driving systems are compatible with these collated screws?
- These collated PPHD screws are designed for use with the Simpson Strong-Tie Quik Drive PROHSD60 and PROHSD60M auto-feed screw driving systems. Two T25 6-lobe driver bits are included in the pack, and replacement bits are available under model QRTX25-1.5.
- Can these screws be used 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 a code-ready solution for structural framing applications.
- What environments are these screws rated for, and what does the Quik Guard coating provide?
- The Quik Guard coating provides corrosion resistance suited for dry service and low-corrosion environments. These screws are also designed for use with some fire-rated sheathing assemblies. They are not intended for high-corrosion or exterior wet-service conditions.
- Do these screws require pre-drilling into cold-formed steel framing?
- No pre-drilling is required. The larger #5 pilot point with a longer flute is designed to pierce cold-formed steel framing directly, allowing the screw to drive through sheathing materials and into CFS efficiently without a separate drilling step.
