S-99017A320 Length 3" Drywall Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various environments
• Effortless installation thanks to the integrated drilling tip that eliminates pre-drilling, saving time and labor costs
• Exceptional holding power from thread forming technology that creates strong, secure threads in drywall and sheet metal
• Wide compatibility with a maximum drilling thickness of 0.105", making them ideal for standard drywall and light-gauge metal applications
• Reduced cam-out and slippage with the Phillips No. 2 drive design, providing better torque transfer and driver control
• Full-length threading ensures consistent grip along the entire 3" length, enhancing pull-out resistance and joint integrity
• Cost-effective fastening solution combining durable materials and efficient design for reliable construction and renovation projects

Professional Applications & Engineering Value

These No. 8 x 3" zinc-plated steel drywall screws are engineered to address common installation challenges in construction and metalworking. The thread forming design displaces material rather than cutting it, creating stronger threads that resist loosening under vibration and load. With a drilling tip and 18 TPI (threads per inch), they penetrate drywall and sheet metal up to 0.105" thick without pilot holes, reducing tool wear and speeding up assembly. The flat head sits flush for a clean finish, while the Phillips drive offers broad tool compatibility. Ideal for drywall-to-stud and light-gauge sheet metal fastening, these screws deliver reliable performance in residential and commercial projects, minimizing rework and ensuring long-term structural stability.

Specification Summary & Compliance

These screws feature a 0.164" thread diameter with 18 TPI and right-hand thread direction, conforming to standard inch measurement practices. The fully threaded shank and standard flat head profile ensure consistent performance. Manufactured from zinc-plated steel, they meet general industry standards for corrosion protection and mechanical properties. While specific compliance certifications are not provided, they are produced to common quality benchmarks suitable for construction and sheet metal applications, ensuring reliable performance in professional settings.
