Professional Applications & Engineering Value

These No. 8 Phillips oval head thread forming screws are engineered specifically for sheet metal applications where reliable fastening is critical. The Black-Oxide Steel construction provides essential corrosion protection while maintaining the structural integrity needed for industrial environments. The thread forming design eliminates the need for pre-tapped holes, creating strong, vibration-resistant threads directly in the material. This makes them ideal for HVAC systems, electrical enclosures, and metal fabrication where sheet metal fasteners must withstand mechanical stress and environmental exposure. The combination of 15 TPI thread pitch and 0.164" thread diameter ensures optimal holding power in thin materials, while the oval head profile with standard dimensions provides both aesthetic appeal and functional seating in countersunk applications.

Specification Summary & Compliance
