S-90330A120 Length 2 1/4" Drywall Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-phosphate steel coating, ideal for indoor environments where moisture may be present.
• Secure, slip-resistant installation thanks to the square drive design that prevents cam-out and ensures consistent torque application.
• Efficient thread forming creates strong, reliable threads in drywall and sheet metal without pre-drilling in materials up to 0.036" thick.
• Optimized grip and reduced material splitting with a pointed tip and 1" minimum thread length for stable fastening in brittle substrates.
• Flush, low-profile finish from the narrow flat head, minimizing surface protrusion for a cleaner appearance in drywall applications.
• Versatile right-hand threading with 18 threads per inch ensures compatibility with standard tools and quick assembly in various construction tasks.
• Durable partial threading provides focused holding power where needed, reducing installation time and improving structural integrity.

Professional Applications & Engineering Value

These No. 6 drywall screws are precision-engineered to address common challenges in drywall and sheet metal fastening, such as material cracking and corrosion. The black-phosphate steel construction offers a protective layer that resists rust, extending the lifespan of installations in humid or variable conditions. With a thread forming design, the screws form their own threads upon insertion, eliminating the need for tapping and reducing labor time. The square drive and flat head profile ensure a tight, flush fit, preventing screw head stripping and providing a smooth surface for finishing. Ideal for contractors and DIY professionals, these screws deliver consistent performance in attaching drywall to metal studs or thin sheet metal, enhancing project efficiency and reliability.
