Professional Applications & Engineering Value
These No. 6 drywall screws deliver exceptional engineering value through their specialized black-phosphate steel construction and thread forming technology. The pointed tip and self-drilling capability eliminate the need for pilot holes, significantly reducing installation time in both drywall and sheet metal applications. The narrow flat head profile ensures countersunk seating without surface protrusion, while the partial threading design provides concentrated gripping power that prevents material cracking and ensures secure fastening. The combination of 18 TPI thread pitch and thread forming method creates permanent, vibration-resistant connections that maintain integrity over time, making these screws ideal for construction projects requiring reliable, long-lasting fastening solutions.
Specification Summary & Compliance
These drywall screws feature precise inch system measurements with a thread diameter of 0.138", length of 1-5/8", and minimum thread length of 1". The right-hand threading follows industry standards with 18 threads per inch for optimal fastening performance. Manufactured from high-quality steel with black-phosphate surface treatment for enhanced durability, these screws are engineered to meet industry specifications for construction and sheet metal fastening applications, ensuring reliable performance and compliance with relevant manufacturing standards.
