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 external hex/slotted drive compatibility with standard tools
- Vibration-resistant locking performance thanks to serrated flange design that prevents loosening under stress
- Reduced installation steps with self-tapping thread forming design that eliminates need for separate tapping operations
- Optimized sheet metal penetration featuring pointed needle tip and 0.159" drill bit compatibility for precise alignment
- Full-thread engagement along the 3/4" length ensures maximum holding power in thin materials up to 0.05" thickness
- Reliable dimensional consistency with No. 10-12 thread specification maintaining precise fit in pre-drilled holes
Professional Applications & Engineering Value
These zinc-plated steel flanged hex tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design creates stronger, more durable threads in parent material by displacing rather than removing metal, resulting in superior resistance to vibration loosening. The combination of external hex drive and serrated locking flange provides dual anti-rotation security, making these No. 10 tapping screws ideal for high-vibration environments where fastener integrity is critical. The fully threaded configuration ensures maximum thread engagement in thin-gauge materials, while the precise 0.19" thread diameter and 12 TPI specification guarantee consistent performance across production runs.
Specification Summary & Compliance
These flanged hex tapping screws feature a No. 10-12 thread specification with 0.19" thread diameter and 3/4" length, designed for use with No. 21 drill bits (0.159" diameter). The thread forming tapping method ensures proper fit in sheet metal applications up to 0.05" thickness. Manufactured from zinc-plated steel with external hex/slotted drive and serrated locking flange, these screws comply with RoHS 3 (2015/863/EU) environmental regulations for industrial use.
