S-90330A500 Length 1 5/8" Drywall Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-phosphate steel coating for extended service life in demanding environments
• Efficient thread forming technology creates strong, secure threads without pre-tapping for faster installation
• Integrated drilling tip eliminates need for pilot holes, reducing labor time and tool requirements
• Optimized thread design with 20 TPI and 7/8" minimum thread length ensures maximum holding power in sheet metal
• Flat head with square drive provides flush finishing and superior torque transmission without cam-out
• Versatile material penetration capable of drilling through up to 0.105" thickness in drywall and sheet metal
• Precision dimensional control ensures consistent performance and reliable fastening in high-volume applications

Professional Applications & Engineering Value

These No. 6 drywall screws are specifically engineered for sheet metal applications where traditional fasteners often struggle with material displacement and thread stripping. The black-phosphate steel construction provides essential corrosion protection in environments where moisture or humidity may be present. The thread forming design creates permanent, high-strength threads in metal substrates without generating chips or debris that can compromise electrical systems or moving parts. The drilling tip with No. 2 point size and 9/64" length penetrates material efficiently, while the partially threaded shank design allows for precise clamping force control. These features combine to solve common installation challenges in HVAC ductwork, electrical enclosures, and metal framing applications where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These drywall screws feature precision Class 2A thread tolerances with 0.138" thread diameter and right-hand threading. The manufacturing process adheres to industry standards for thread forming screws, ensuring consistent performance across production runs. The flat head profile with narrow design and square drive No. 1 provides secure tool engagement. Compliance includes meeting relevant industrial fastening specifications for construction and sheet metal applications, with materials and coatings manufactured to support RoHS and REACH environmental standards for safe usage in commercial and residential projects.
