PROTWIST 10X3-1/2 SD | PRO-SD312

Pro-Twist's #10 x 3-1/2 in. Phillips Bugle-Head Fine-Thread Self-Drill Black Phosphate Drywall Screws are optimized for consistent drive performance using a Phillips recess that supports controlled installation with screw guns or drills. The longer 3-1/2 in. length is well suited for layered assemblies and deeper penetration into metal framing. The black phosphate coating enhances corrosion resistance in interior environments and improves joint compound adhesion. Packaged in a 1,000 count box, these screws support contractors and installers who demand strength, reliability, and productivity on large drywall projects.
