Product Description
The Simpson Strong-Drive PPHD Sheathing-to-CFS Screw is an engineered fastener purpose-built for attaching sheathing materials directly into cold-formed steel (CFS) framing. Its larger #5 pilot point with extended flute and aggressive buttress thread design with dog-ear point work together to push through sheathing and metal faster, while the flat head profile sits flush for clean, professional results. Collated for use with Simpson Quik Drive auto-feed screw driving systems, this screw is equally suited to high-volume framing and structural panel installations in residential, agricultural, and commercial construction.
Key Features
- Larger #5 pilot point with longer flute - starts drilling faster and with less resistance, reducing fatigue and boosting productivity on the job site
- Buttress threads and dog-ear point - drive through sheathing and metal more quickly than standard thread profiles, cutting down installation time when securing panels to CFS framing
- T25 6-lobe recess - delivers a more secure engagement between bit and fastener, minimizing cam-out and keeping drives consistent even at high speed
- Compatible with Quik Drive PRO300SG2, PRO250G2, and PRO200SG2 auto-feed systems - slots directly into the collated driving systems many crews already own, enabling continuous, hands-free fastening without pausing to reload
- Two T25 6-lobe driver bits included (replacement model QRTX25-1.5) - lets crews get started immediately without a separate bit purchase, and a known replacement model makes restocking simple
- Quik Guard coating - provides protection suited to dry service and low-corrosion environments, including select fire-rated sheathing assemblies, so the fastener holds up in the conditions where CFS framing is most commonly used
- Code-recognized for shearwalls and diaphragms per AISI S240 and AISI S400 - meets the requirements for structural lateral-force applications in both residential and commercial projects, reducing the need for engineering substitutions
Why This Product
- Built specifically for sheathing-to-CFS connections - unlike general-purpose metal screws, the PPHD is engineered from the point up for the exact task of penetrating sheathing and biting into cold-formed steel, giving installers a fastener that performs correctly the first time rather than requiring trial and error with off-spec alternatives
- Collated format pairs with widely used Quik Drive systems - compatibility with the PRO200SG2, PRO250G2, and PRO300SG2 means this screw integrates directly into a proven auto-feed workflow, dramatically reducing per-fastener installation time on large wall or floor sheathing runs
- Structural code compliance built in - recognition under AISI S240 and AISI S400 for shearwall and diaphragm use means contractors can specify these screws with confidence on permitted projects without sourcing separate engineering documentation
- Everything needed to start driving is included - with two T25 driver bits in the package and a clear replacement bit model number, there is no gap between opening the box and getting to work, making the PPHD a practical choice for crews managing tight schedules
