S-90064A580 Length 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 installation efficiency through integrated drilling tip that eliminates pre-drilling requirements in steel and sheet metal
• Secure fastening performance with thread forming technology that creates stronger, vibration-resistant connections
• Optimized torque transmission via external hex head design for reliable installation with standard tools
• Increased load distribution from flanged design that provides wider bearing surface and prevents pull-through
• Full-length thread engagement ensuring maximum holding power across the entire 3/4" length
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws deliver exceptional engineering value in steel and sheet metal applications where reliability is critical. The thread forming design creates precise, permanent threads in base materials without generating chips, eliminating contamination risks in sensitive assemblies. The integrated drilling tip with No. 3 geometry penetrates up to 0.187" thickness, streamlining installation by combining drilling and tapping operations. The external hex drive provides superior torque transmission compared to Phillips or slotted drives, reducing cam-out incidents during high-torque installations. The flanged head distributes clamping force over a wider area (0.432" diameter), preventing material distortion in thin-gauge applications while the zinc plating offers reliable corrosion protection for long-term performance in industrial environments.

Specification Summary & Compliance

These thread forming screws feature a No. 12 size with 0.216" thread diameter and 14 threads per inch, manufactured to BSD tapping screw standards. The fully threaded 3/4" length ensures complete engagement while the external hex head (0.313" width, 0.194" height) provides reliable drive performance. The screws are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety regulations for industrial components. The drilling tip (9/32" length, No. 3 type) is optimized for maximum drilling thickness of 0.187" in steel and sheet metal applications.
