S-90093A227 Length 1" Drywall Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-phosphate coating, ideal for interior drywall and sheet metal applications where moisture may be present.
• Eliminates pre-drilling thanks to the integrated drilling tip (No. 2 size), allowing for faster installation and reduced labor costs.
• Superior material displacement and holding power from the thread-forming design, creating strong, reliable threads in the base material.
• Full-length threading ensures maximum grip along the entire 1" length, providing consistent clamping force and preventing loosening.
• Streamlined installation with a standard Phillips Flat Head (No. 2 drive) that sits flush with the surface for a clean, professional finish.
• Optimized for common materials with a 0.164" thread diameter and 18 TPI, designed specifically for efficient fastening in drywall and sheet metal up to 0.105" thick.
• Reduced cam-out and driver slippage with the precise Phillips drive, enhancing application speed and bit life.

Professional Applications & Engineering Value

These No. 8 x 1" drywall screws are engineered to solve common installation challenges in construction and metalworking. The thread-forming design displaces material to create robust, permanent threads without the need for pre-tapping, significantly speeding up assembly in drywall and sheet metal applications. The self-drilling tip (Drill Point Size No. 2) penetrates materials up to 0.105" thick, eliminating a separate drilling step and reducing the risk of material splitting or misalignment. Combined with the black-phosphate steel construction, these fully threaded screws offer a reliable, corrosion-resistant fastening solution that maintains integrity in various interior environments, ensuring long-term performance and reducing callbacks.

Specification Summary & Compliance

This product adheres to standard inch system measurements with a thread diameter of 0.164" and approximately 18 threads per inch (TPI). The flat head features a standard profile and a No. 2 Phillips drive. Manufactured from steel with a black-phosphate finish for corrosion protection, these screws are thread-forming and fully threaded with a right-hand thread direction. They are designed for general use in drywall and sheet metal and are compliant with industry-standard specifications for such applications.
