Description
Fast and reliable for attaching sheathing or sub-floor panels to steel framing, the Strong-Drive PPHDQ11516B-4K PPHD Sheathing-to-CFS Screw is engineered to drill through panel layers and into cold-formed steel (CFS) framing without pre-drilling. With its longer #5 pilot point, fine thread design, flat head and six-lobe drive, this screw is built to deliver strong engagement, clean seating and efficient installation for professionals and DIYers alike.
Key Features
- Self-Drilling #5 Point: Easily penetrates panel materials and CFS framing without the need for pre-drilling.
- Fine Threads: Provides excellent pull-through resistance and strong retention in steel and wood substrates. Buttress threads available in #8 sizes for added holding power.
- Flat Countersunk Head with 6-Lobe Drive: Ensures flush installation with reliable tool engagement using a T25 driver bit.
- Corrosion-Resistant Coatings: Available in yellow zinc for dry interior use or Quik Guard coating for moderate exterior exposure.
- Collated and Bulk Options: Compatible with both hand-drive and auto-feed screw-driving systems to increase speed on large jobs.
Applications
- Attaching OSB, plywood, gypsum board or other sheathing to cold-formed steel framing in walls, floors or ceilings.
- Installing subfloors over steel joists in residential or commercial framing.
- Use in diaphragm-rated assemblies and structural shear walls that require fastener code compliance.
- Ideal for both new construction and renovation projects involving steel stud or track assemblies.
Installation
- Select the appropriate length and diameter based on panel thickness and steel gauge to ensure proper thread engagement.
- Use a T25 6-lobe driver bit in a screw gun or drill with clutch control to avoid overdriving the screw head.
- Align screw perpendicular to the sheathing surface and drive until the head is flush with the panel material.
- If using collated screws, confirm compatibility with auto-feed systems and adjust feed settings as required.
- Choose the correct finish for the application environment. Use yellow zinc for dry interiors and Quik Guard for exposed or humid areas.
- Follow manufacturer spacing and pattern guidelines to meet load-bearing and code-compliant installation standards.
