Product Description
The Simpson Strong-Drive PPHD Sheathing-to-CFS Screw (Model PPHDQ11516S0817) is an engineered fastening solution purpose-built to drive through sheathing materials and directly into cold-formed steel (CFS). Featuring a long #5 drill point with extended flute and an aggressive buttress thread design with dog-ear point, this #8 x 1-15/16 in. screw achieves faster penetration through sheathing and metal substrates while delivering a tight, secure connection. The flat head profile sits flush for clean, professional results, and the T25 6-lobe recess minimizes cam-out for a more controlled, reliable drive.
This collated format is designed for compatibility with the Simpson Strong-Tie Quik Drive PRO200SG2, PRO250G2, and PRO300SG2 auto-feed screw driving systems, enabling high-volume installation with consistent depth and placement. Protected by a Quik Guard coating, these screws are suited for dry service and low-corrosion environments, including select fire-rated sheathing assemblies. Sold in a 2,000-count package with two T25 6-lobe driver bits included, the PPHDQ11516S0817 is a code-recognized fastener for shearwall and diaphragm applications per AISI S240 and AISI S400.
