S-90093A231 Length 1 5/8" Drywall Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-phosphate steel coating, extending screw life in demanding environments like construction and metalwork.
• Effortless installation thanks to the specialized No. 2 drill tip that self-penetrates up to 0.105" thickness, reducing pre-drilling needs and speeding up projects.
• Exceptional holding power from thread forming technology, which creates strong, secure threads in drywall and sheet metal for reliable, long-term fastening.
• Wide compatibility with a fully threaded No. 8 size and 18 threads per inch, ensuring consistent performance across various drywall and metal applications.
• Reduced cam-out and slippage with the Phillips No. 2 drive, providing better torque control and minimizing tool wear during installation.
• Streamlined, flush finishes enabled by the standard flat head profile, ideal for applications where a smooth surface is critical.
• Enhanced durability in harsh conditions due to the robust steel material and right-hand threading, designed for repeated use in industrial settings.

Professional Applications & Engineering Value

These No. 8 drywall screws are engineered to address common installation challenges in drywall and sheet metal projects. The black-phosphate coating provides a protective layer that resists rust and wear, crucial for maintaining integrity in humid or abrasive environments. With a thread forming design, the screws displace material to form precise threads, eliminating the risk of stripping and ensuring a tight, vibration-resistant hold. The integrated drill tip (No. 2 size) allows for quick penetration without pre-drilling, saving time and labor in high-volume construction or metal fabrication. This combination of fully threaded engagement and Phillips drive efficiency makes them a reliable choice for professionals seeking durability and ease of use in fastening applications.

Specification Summary & Compliance

These screws adhere to standard inch measurements, with a thread diameter of 0.164" and length of 1-5/8". They feature a right-hand thread with approximately 18 threads per inch, ensuring compatibility with common fastening systems. The flat head and Phillips No. 2 drive are designed for precise installation, while the thread forming method enhances grip without requiring tapped holes. Manufactured from high-quality steel, they comply with industry norms for construction and metalworking, and are suitable for use in environments requiring reliable, corrosion-resistant fasteners. While specific standards like RoHS or ASME are not detailed, the design focuses on practical performance in drywall and sheet metal applications.
