Key Features & Benefits at a Glance
- Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.098" steel and sheet metal
- Superior corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
- Enhanced load distribution from the wide flanged truss head design that resists pull-through and provides secure fastening
- Optimized thread engagement with fully threaded No. 8 (0.164") diameter and 18 TPI right-hand thread forming design
- Secure installation control via Phillips No. 2 drive that prevents cam-out during high-torque applications
- Reliable material displacement through BSD thread forming technology that creates strong, permanent threads in parent material
- Environmental compliance assurance meeting RoHS 3 standards for safe industrial usage
Professional Applications & Engineering Value
These zinc-plated steel tapping screws deliver exceptional value in steel and sheet metal fabrication where traditional fastening methods prove inefficient. The thread forming BSD design eliminates chip accumulation issues common with thread-cutting alternatives, while the flanged truss head provides superior clamping force across wider surface areas. The integrated No. 2 drilling tip penetrates up to 0.098" material thickness without pilot holes, significantly reducing installation time in high-volume assembly operations. Engineered for industrial fastener applications requiring consistent performance in HVAC systems, electrical enclosures, and metal framing assemblies where vibration resistance and long-term reliability are critical.
Specification Summary & Compliance
This No. 8 x 3" tapping screw features precise 0.164" thread diameter with 18 TPI right-hand threads in a fully threaded configuration. Manufactured to BSD screw type standards for thread forming applications in steel and sheet metal substrates. The zinc-plated steel construction provides corrosion protection while maintaining RoHS 3 (2015/863/EU) compliance for environmental safety. The Phillips No. 2 drive system ensures compatibility with standard industrial drivers, while the 0.44" flange diameter and truss head profile deliver optimal load distribution.
