• Optimized for sheet metal applications with drilling capability up to 0.105" thickness and precise No. 10 screw sizing
• Enhanced holding power through 16 threads per inch configuration that ensures superior grip in drywall and metal substrates
• Environmental compliance assurance with RoHS 3 certification for safe, regulated use in commercial projects
• Streamlined installation profile with flat head design that sits flush with material surfaces for clean finishes

Professional Applications & Engineering Value

These zinc-plated steel drywall screws are engineered specifically for sheet metal and drywall applications where reliability and installation efficiency are paramount. The thread forming technology creates stronger, more durable connections by displacing material rather than removing it, resulting in superior resistance to vibration loosening and pull-out forces. The specialized drilling tip with No. 2 point size eliminates the need for pre-drilling in materials up to 0.105" thickness, significantly reducing labor time and tool requirements. The fully threaded design ensures maximum engagement along the entire screw length, while the Phillips flat head provides a clean, flush finish that's ideal for visible applications. These engineering features combine to deliver consistent performance in commercial construction, HVAC installations, and metal framing projects where joint integrity is critical.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.19" thread diameter and 16 threads per inch configuration, these screws ensure consistent performance across applications. The thread forming tapping method and right-hand thread direction follow industry-standard installation protocols. Compliance with RoHS 3 (2015/863/EU) regulations ensures environmental safety and material restrictions are met for international projects. The combination of zinc-plated steel material and standardized No. 10 screw size with 1-1/4" length provides reliable, specification-compliant fastening solutions for professional contractors and industrial applications.
