S-90093A234 Length 2 1/4" Drywall Screws

Key Features & Benefits at a Glance

• Self-drilling design eliminates pre-drilling, saving significant labor time and reducing tool wear in high-volume drywall and sheet metal installations.
• Black-phosphate steel coating provides superior corrosion resistance, ensuring long-term fastener integrity in various construction environments.
• No. 2 drill point efficiently penetrates up to 0.105" thickness, delivering reliable performance in standard drywall and light-gauge metal applications.
• Fully threaded shank maximizes pull-out resistance, creating a secure, vibration-resistant hold that prevents material loosening over time.
• Phillips flat head design sits flush with material surfaces, providing a clean finished appearance while preventing snagging hazards.
• Thread forming technology creates stronger mating threads, reducing the risk of stripping and ensuring consistent clamping force.
• Precision-manufactured right-hand threads with 18 TPI guarantee smooth driving and optimal engagement in various substrate materials.

Professional Applications & Engineering Value

These self-drilling drywall screws solve critical installation challenges by combining black-phosphate steel durability with advanced thread forming technology. The integrated No. 2 drill point eliminates the need for separate pilot holes, dramatically reducing installation time and labor costs in commercial drywall construction and sheet metal fabrication. The fully threaded design ensures maximum thread engagement throughout the entire fastener length, providing exceptional pull-out strength that prevents sagging drywall or loosening metal panels. The Phillips flat head configuration allows for flush mounting without protrusions, creating safer work environments while maintaining aesthetic appeal in finished spaces. Engineered for repetitive use in demanding conditions, these screws deliver consistent performance across multiple applications while minimizing installation errors and callbacks.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread tolerances for consistent driving performance. The right-hand threads maintain 18 threads per inch specification throughout the 2-1/4" length. Complies with industry-standard manufacturing specifications for self-drilling screws and contains RoHS-compliant black-phosphate surface treatment. The flat head profile and Phillips drive system conform to established fastener engineering standards for construction applications.
