Professional Applications & Engineering Value

These No. 6 drywall screws with thread forming technology deliver exceptional performance in commercial construction and metal fabrication applications. The black-phosphate steel construction provides essential corrosion protection while maintaining the strength required for demanding environments. The integrated self-drilling capability with No. 2 drill point eliminates the need for separate drilling operations, significantly reducing labor costs and installation time in sheet metal and drywall applications. The fully threaded 20 TPI design ensures maximum thread engagement and superior pull-out resistance, while the Phillips flat head configuration allows for clean, flush installations that meet professional finishing standards. These thread forming screws create permanent, vibration-resistant connections that maintain integrity under stress.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.138" thread diameter and 1-5/8" length, these screws feature right-hand threading with consistent 20 TPI spacing. The flat head profile maintains standard geometry with 0.334" head diameter and 0.031" head height for uniform installation. The thread forming tapping method ensures reliable performance without thread stripping. These fasteners comply with industry standards for construction screws and are suitable for professional drywall and sheet metal applications requiring self-drilling capability and corrosion-resistant black-phosphate steel construction.
