S-90064A610 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.21" thickness in steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
• Enhanced installation efficiency with external hex drive design providing maximum torque transmission and slip resistance
• Permanent thread formation through thread forming technology that creates stronger, vibration-resistant connections in parent material
• Distributed load bearing with flanged head design that increases clamping surface area and prevents pull-through
• Full-length thread engagement ensures consistent holding power along the entire 3/4" length for maximum fastening security
• Optimized for high-volume assembly with right-hand threading compatible with standard power tools and production line processes

Professional Applications & Engineering Value

These 1/4"-14 thread forming tapping screws deliver exceptional engineering value by addressing critical challenges in metal fabrication and assembly operations. The zinc-plated steel construction provides essential corrosion protection for industrial environments while maintaining high tensile strength. The innovative thread forming design creates permanent, zero-clearance threads in steel and sheet metal substrates, eliminating the need for separate tapping operations and reducing installation time by up to 50%. The flanged hex head with external drive system ensures reliable torque transmission without cam-out, while the integrated drilling tip penetrates materials up to 0.21" thick without pilot holes. This combination of features makes these BSD tapping screws ideal for HVAC systems, electrical enclosures, automotive components, and structural metal assemblies where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

These industrial fasteners feature precision 1/4"-14 threads with standard right-hand threading and fully threaded shank design. The screws conform to BSD (British Standard Dimension) specifications for tapping screws and feature a No. 3 drill tip optimized for metal penetration. Manufacturing complies with industry standards for dimensional accuracy, including proper head height (0.24") and flange diameter (0.52") tolerances. The zinc plating surface treatment provides corrosion protection while maintaining compliance with RoHS and REACH environmental directives for industrial components.
