Key Features & Benefits at a Glance
- Eliminates pre-drilling requirements with integrated drilling tip technology 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 truss head and integrated flange design that prevents pull-through
- Secure thread-forming installation with fully threaded 0.164" diameter BSD profile creating permanent, vibration-resistant connections
- Optimized driving efficiency with Phillips No. 2 drive that provides reliable torque transfer during installation
- Maximum material compatibility specifically engineered for steel and sheet metal applications with 18 TPI thread engagement
- Regulatory compliance assurance 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 fabrication where traditional fastening methods require multiple steps. The thread forming BSD design creates precise, cold-formed threads that eliminate the need for separate tapping operations, significantly reducing assembly time and labor costs. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the flanged truss head distributes clamping force across a wider surface area, preventing material deformation in thin-gauge applications. The integrated drilling tip technology with 5/32" penetration capability ensures immediate engagement without pilot holes, making these Phillips drive screws ideal for high-volume production lines where efficiency and reliability are critical.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.164" thread diameter and 18 TPI right-hand threads in thread forming style. Features fully threaded 1-3/8" length with No. 8 screw size and 0.44" flange diameter. Complies with RoHS 3 (2015/863/EU) environmental regulations and engineered for BSD tapping screw applications in steel and sheet metal up to 0.098" thickness.
