S-90064A729 Length 1 5/8" 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 installation efficiency through integrated drilling tip that eliminates pre-drilling requirements for materials up to 0.098" thickness
• Exceptional holding power achieved through thread-forming design that creates strong, permanent threads in steel and sheet metal
• Secure flange design provides wider bearing surface for improved load distribution and vibration resistance
• Optimized drive performance with 1/4" external hex head ensuring reliable torque transmission and reduced tool slippage
• Full-thread engagement along the 1-5/8" length delivers maximum pull-out strength and structural integrity
• Industry-standard compatibility with BSD tapping screw specifications for reliable performance across metalworking applications

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional engineering value by addressing critical challenges in metal assembly operations. The thread-forming design eliminates the need for separate tapping operations, significantly reducing installation time while creating stronger, more reliable threads in steel and sheet metal applications. The integrated drilling tip with No. 2 point specification penetrates materials up to 0.098" thick without pre-drilling, preventing material displacement and ensuring precise alignment. The flanged hex head configuration provides superior clamping force distribution, making these BSD tapping screws ideal for high-vibration environments where fastener integrity is critical. The combination of fully threaded shank and external hex drive ensures maximum engagement and reliable installation across industrial metal fabrication, HVAC systems, and automotive assembly applications.

Specification Summary & Compliance

These tapping screws feature precise 0.164" thread diameter with 18 threads per inch in right-hand orientation, manufactured to BSD standards for consistent performance. The thread-forming tapping method ensures reliable engagement without chip removal, while the zinc-plated steel construction provides corrosion protection for extended service life. The fasteners comply with industry standards for dimensional accuracy and are suitable for various industrial fastener applications requiring reliable performance in metal substrates.
