S-90093A236 Length 3 1/2" Drywall Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-phosphate steel coating for longer service life in various environments
• Superior drilling efficiency with No. 2 drill tip that penetrates up to 0.105" thickness without pre-drilling
• Excellent holding power through thread-forming technology that creates strong, secure connections in drywall and sheet metal
• Optimized installation speed with Phillips flat head design that prevents cam-out and ensures smooth driving
• Reduced material splitting with partially threaded shank that minimizes stress on drywall and sheet metal
• Reliable performance with 18 TPI right-hand thread pattern for consistent fastening results
• Versatile application capability suitable for both drywall installation and sheet metal fabrication projects

Professional Applications & Engineering Value

These No. 8 drywall screws are engineered to address common installation challenges in construction and metalworking applications. The black-phosphate steel construction provides essential corrosion protection while maintaining structural integrity. The innovative thread-forming technology eliminates the need for separate tapping operations, creating stronger threads in both drywall and sheet metal substrates. The specialized No. 2 drill tip with 3/16" length ensures clean penetration without material tear-out, while the partially threaded design prevents over-tightening and material damage. The Phillips flat head sits flush with surfaces for professional finishes, making these thread forming screws ideal for contractors seeking efficiency and reliability in drywall installation and light gauge metal applications.

Specification Summary & Compliance

These drywall screws feature precision 0.164" thread diameter with 18 TPI thread spacing and 3-1/2" length for optimal fastening performance. Manufactured to industry standards with right-hand threading and standard flat head profile for consistent installation. The thread forming design ensures secure fastening without pre-tapped holes. Compliant with relevant industrial fastening specifications and manufactured using black-phosphate steel that meets industry requirements for construction and metalworking applications.
