S-91515A347 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.11" thickness in steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
• Enhanced driving stability with Phillips No. 2 drive system preventing cam-out during high-torque installation
• Maximum material engagement through fully threaded design ensuring superior pull-out resistance in demanding applications
• Distributed bearing surface with 0.452" flange diameter reducing surface pressure and preventing material deformation
• Reliable thread-forming performance with BSD tapping method creating strong, permanent threads in parent material
• Optimized for production efficiency with right-hand threading and 14 TPI configuration for rapid installation cycles

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in steel and sheet metal fabrication by eliminating secondary drilling operations. The precision No. 2 drilling tip combined with thread-forming BSD technology creates clean, secure threads without pre-tapped holes, significantly reducing assembly time and labor costs. The flanged truss head design provides wide bearing surface distribution, preventing pull-through in thin-gauge materials while maintaining consistent clamping force. Engineered for high-volume production environments, these fully threaded screws ensure reliable performance in HVAC systems, electrical enclosures, automotive components, and industrial equipment where vibration resistance and long-term durability are critical.

Specification Summary & Compliance

These tapping screws feature precise 0.216" thread diameter with 14 threads per inch and 5/8" length, manufactured to BSD thread-forming standards for consistent performance. The Phillips No. 2 drive ensures compatibility with standard industrial drivers, while the zinc-plated steel construction provides reliable corrosion protection. All components are RoHS 3 (2015/863/EU) Compliant, meeting international environmental regulations for hazardous substance restrictions in electrical and electronic equipment applications.
