Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
- Enhanced material penetration through self-drilling tip design that eliminates pre-drilling requirements in steel and sheet metal up to 0.098" thickness
- Increased fastening stability with flanged truss head design that provides wider bearing surface and prevents pull-through
- Optimized thread engagement through BSD thread-forming technology that creates strong, permanent threads in parent material
- Reliable installation performance with Phillips No. 2 drive system ensuring secure tool engagement and reduced cam-out risk
- Full-length threading (18 TPI) delivers maximum grip strength and uniform stress distribution along the entire fastener length
- Environmental compliance assurance with RoHS 3 certification for safe use in regulated industrial applications
Professional Applications & Engineering Value
These No. 8 zinc-plated steel tapping screws deliver exceptional engineering value in steel and sheet metal fabrication applications. The combination of thread-forming BSD design and self-drilling tip eliminates multiple installation steps, significantly reducing assembly time and labor costs. The flanged truss head provides superior clamp load distribution, preventing material deformation in thin-gauge applications while the zinc plating offers reliable protection against corrosion in industrial environments. With fully threaded 0.164" diameter construction and Phillips drive compatibility, these screws ensure consistent performance in high-volume production settings where reliability and efficiency are critical.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.164" thread diameter and 18 TPI right-hand threads. Features thread-forming BSD tapping method and fully threaded design for maximum holding power. Compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use across industrial sectors. The flanged truss head with Phillips No. 2 drive provides standardized installation compatibility while the self-drilling tip (No. 2 type) delivers consistent penetration performance in specified material thicknesses.
