S-90093A217 Length 2 1/2" Drywall Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black phosphate coating that protects against rust in demanding construction environments
• Enhanced holding power through thread forming technology that creates stronger, more permanent connections in drywall and sheet metal
• Efficient installation with self-drilling tip that eliminates pre-drilling and penetrates up to 0.105" thickness
• Clean, flush finish with flat head design that sits perfectly flush with material surfaces
• Reduced cam-out with Phillips No. 2 drive that provides better torque transfer and driver engagement
• Optimized thread engagement with 20 TPI thread pitch that ensures maximum pull-out resistance
• Versatile fastening solution suitable for both drywall and sheet metal applications with reliable performance

Professional Applications & Engineering Value

These black phosphate steel drywall screws are engineered to address common challenges in construction and metalworking applications. The thread forming technology creates precise, tight-fitting threads that significantly improve pull-out resistance compared to conventional screws, making them ideal for securing drywall to metal studs or joining sheet metal components. The self-drilling tip eliminates the need for pilot holes, reducing installation time and labor costs while maintaining precise alignment. The partially threaded design ensures optimal clamping force distribution, preventing material distortion in delicate drywall applications. With their right-hand threading and Phillips drive system, these screws provide reliable performance in high-volume professional settings where speed and durability are critical factors.

Specification Summary & Compliance

These No. 6 x 2-1/2" drywall screws feature precise 0.138" thread diameter with 20 TPI thread pitch and comply with standard inch measurement specifications. The thread forming manufacturing process ensures consistent thread quality and dimensional accuracy. The black phosphate surface treatment provides corrosion protection while maintaining electrical conductivity where required. These screws are manufactured to meet industry standards for construction fasteners and are suitable for professional drywall installation and sheet metal fabrication applications, ensuring reliable performance and compliance with building code requirements for structural fastening systems.
