Product Description
The Simpson Strong-Tie Strong-Drive PPHD Sheathing-to-CFS Screw (Model PPHDQ134S1016) is an engineered fastener purpose-built for attaching sheathing materials to cold-formed steel (CFS) framing. This #10 x 1-3/4 in. collated screw features a long #5 pilot point with an extended flute to cleanly pierce and self-drill through sheathing and into CFS without pre-drilling. Its fine-thread, flat-head design pulls the sheathing tight to the steel substrate, while the 6-lobe T25 recess ensures a more secure bit engagement and reduces cam-out during high-volume installation. Protected by a Quik Guard coating, these screws are suited for dry service, low-corrosion environments and select fire-rated sheathing assemblies. This collated format is designed for use with the Simpson Strong-Tie Quik Drive PRO200SG2, PRO250G2, and PRO300SG2 auto-feed screw driving systems, delivering fast, consistent fastening across residential, agricultural, and commercial projects. Each package contains 2,000 screws plus two T25 6-lobe driver bits.
