Simpson Strong-Tie (Pleasanton, CA) has introduced the Strong-Drive PPHD Sheathing-to-CFS screw, a multipurpose, self-drilling pilot point screw suitable for attaching sheathing, drywall, or subflooring to cold-formed steel framing.
Designed as an update to the existing PPSD Sheathing-to-CFS screw, the PPHD features a larger #5 pilot point with a longer flute and comes in popular #8 sizes. In addition, the fastener has buttress threads and a new dog-eared point for improved drilling performance through sheathing and metal.
PPHD screws can be purchased in bulk quantities for hand-drive applications or collated for auto-feed driving with the Simpson Strong-Tie® Quik Drive® PRO300SG2, PRO250G2, and PRO200SG2 auto-feed screw driving systems. The fasteners are also available in two levels of corrosion resistance — the Quik Guard coating is suitable for a wide variety of exterior applications and the yellow-zinc coating is for dry-service and low-corrosion environments.
Available in a #8 x 1 15/16"; #10 x 1 3/4", 11 5/16" and 3"; and #12 x 1 3/4" sizes, the PPHD Sheathing-to-CFS screws have a 6-lobe recess for secure driving and can be used as prescribed by the codes for shearwalls and diaphragms as set forth in AISI S240 and AISI S400.
