S-90091A114 Length 2 1/4" Drywall Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-phosphate steel coating that protects against rust in various environmental conditions
• Enhanced holding power through thread forming design that creates strong, permanent threads without pre-drilling in many materials
• Clean, flush installation with narrow flat head profile that sits perfectly flush with surfaces for professional finishes
• Optimized thread engagement with 1-1/2" thread length providing maximum grip in drywall and sheet metal applications
• Wide material compatibility capable of fastening up to 0.036" thickness in both drywall and sheet metal substrates
• Reliable drive performance with Phillips No. 1 drive that prevents cam-out and ensures consistent installation torque
• Precision threading with 18 threads per inch and 0.138" diameter for secure, vibration-resistant connections

Professional Applications & Engineering Value

These No. 6 drywall screws are engineered specifically for demanding construction and metalworking applications where reliability is paramount. The black-phosphate steel construction provides exceptional corrosion protection, making these fasteners ideal for interior environments where moisture resistance is required. The thread forming technology creates stronger thread engagement by displacing material rather than removing it, resulting in superior pull-out resistance compared to conventional tapping screws. This is particularly valuable in sheet metal applications where stripped threads can compromise structural integrity. The partially threaded design with pointed tip ensures easy starting and precise placement, while the narrow flat head profile delivers a clean, professional appearance that requires no additional finishing work. These screws are optimized for drywall installation where consistent performance and reliable holding power are essential for long-term durability.

Specification Summary & Compliance

These inch-system fasteners feature precision right-hand threads with 18 TPI (threads per inch) and 0.138" thread diameter, manufactured to industry standards for dimensional accuracy. The partially threaded configuration provides 1-1/2" of active thread length with a pointed tip for easy penetration. The Phillips drive (No. 1 size) ensures compatibility with standard installation tools. These thread forming screws are manufactured from high-quality steel with black-phosphate surface treatment for enhanced corrosion resistance. The fasteners comply with relevant industry specifications for construction and metal fastening applications, providing reliable performance in professional drywall and sheet metal installations with maximum drilling capacity of 0.036" thickness.
