S-90064A731 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced driving efficiency with 1/4" external hex head design providing secure tool engagement and reduced slippage
• Self-drilling capability with specialized No. 2 drill tip that eliminates pre-drilling requirements, saving installation time and labor costs
• Maximum material penetration with drilling tip designed to penetrate up to 0.098" thickness in steel and sheet metal applications
• Exceptional holding power through BSD thread forming technology that creates strong, permanent threads without chip formation
• Full-length threading ensures consistent engagement and uniform stress distribution along the entire 1-3/4" length
• Integrated flange design provides wider bearing surface for improved load distribution and vibration resistance

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws are engineered specifically for challenging steel and sheet metal applications where traditional fasteners fail. The thread forming BSD technology creates precise, durable threads without generating chips or debris, eliminating contamination concerns in sensitive assemblies. The combination of external hex drive and flanged design ensures maximum torque transmission while preventing head stripping, making them ideal for high-vibration environments. The integrated drilling tip with 3/16" length streamlines installation by eliminating separate drilling operations, significantly reducing assembly time in manufacturing, construction, and metal fabrication projects. These industrial fasteners maintain consistent performance across temperature variations and mechanical stresses, providing reliable long-term fastening solutions.
