Product Description
The Simpson Strong-Tie Strong-Drive PPHD Sheathing-to-CFS Screw - #10 x 1-3/4 in., T25 6-Lobe, Yellow Zinc (4,000-Pack, Model PPHD134B1016-4K) is an engineered fastener purpose-built for driving through sheathing materials and into cold-formed steel (CFS) framing. Its enlarged #5 pilot point with a longer flute starts cleanly and drives without pre-drilling, while the fine-thread, buttressed design bites securely into CFS for consistent, code-compliant holding strength. The yellow-zinc coating provides corrosion resistance suitable for dry service and low-corrosion environments. These screws come in bulk form for hand-drive applications and are also compatible with Quik Drive auto-feed screw driving systems - making them equally at home on large commercial decks and residential shearwall assemblies. At 4,000 fasteners per package, this bulk pack is sized for high-volume structural sheathing work.
Key Features
- Larger #5 pilot point with longer flute - drives through sheathing and into CFS without pre-drilling for fast, reliable starts
- Fine threads (16 TPI) - maximize thread engagement in cold-formed steel for superior pull-out resistance
- T25 6-lobe recess - delivers a more secure, cam-out-resistant drive compared to standard Phillips or square drives
- Code-recognized for shearwalls and diaphragms - PPHD screws may be used as prescribed by the codes for shearwalls and diaphragms as described in AISI S240 and AISI S400
- Flat head profile (0.323 in. diameter) - seats flush with sheathing surfaces for a clean, professional finish
- Yellow-zinc coating - designed for use in dry service, low-corrosion environments and some fire-rated sheathing assemblies
- Bulk 4,000-count packaging - optimized for high-volume sheathing applications; compatible with Quik Drive auto-feed systems
- Maximum installation thickness: two layers of 12 ga. (0.218 in. total)

Frequently Asked Questions
- What is the maximum steel thickness these screws can fasten through?
- These screws are rated for a maximum thickness of two layers of 12-gauge steel, with a combined total thickness of 0.218 inches. They are specifically designed for fastening wood sheathing materials to cold-formed steel (CFS) framing.
- Are these screws approved for use in shearwall and diaphragm assemblies?
- 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 code-compliant residential, agricultural, and commercial structural applications.
- Do these screws require pre-drilling before installation?
- No pre-drilling is required. The enlarged #5 pilot point with a longer flute is designed to start cleanly and drive directly through sheathing materials and into cold-formed steel without the need for a pilot hole.
- Can these screws be used with an auto-feed screw driving system?
- Yes. These screws are compatible with Quik Drive auto-feed screw driving systems in addition to standard hand-drive applications, making them well-suited for high-volume sheathing work on large commercial or residential projects.
