Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
- Efficient installation through thread-forming BSD technology that creates stronger mating threads without pre-tapping
- Enhanced drilling capability with specialized No. 2 drill tip that penetrates up to 0.098" thickness in steel and sheet metal
- Increased bearing surface from the wide truss head design that distributes load more effectively and resists pull-through
- Secure fastening with fully threaded 0.164" diameter shank providing maximum grip length and holding power
- Quick installation using Phillips No. 2 drive that offers familiar, reliable driving with standard tools
- Regulatory compliance meeting RoHS 3 standards for environmentally responsible manufacturing
Professional Applications & Engineering Value
These No. 8 tapping screws deliver exceptional value in steel and sheet metal applications where reliable fastening is critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the thread-forming BSD technology eliminates the need for pre-tapped holes, reducing installation time and labor costs. The specialized drilling tip penetrates up to 0.098" thickness, making these Phillips drive screws ideal for assembling electrical enclosures, HVAC components, and metal framing systems. The flanged truss head design offers superior load distribution, preventing material deformation in thin-gauge metals and ensuring long-term joint integrity.
Specification Summary & Compliance
These tapping screws feature precise 0.164" thread diameter with 18 TPI right-hand threading and fully threaded design for maximum engagement. Manufactured to BSD tapping screw standards with thread-forming technology that creates secure mating threads in base materials. The screws comply with RoHS 3 (2015/863/EU) regulations and are engineered for reliable performance in steel and sheet metal fastening applications with a maximum drilling capacity of 0.098" thickness.
