Key Features & Benefits at a Glance
- Eliminates pre-drilling with integrated No. 2 drill tip, saving significant labor time and tooling costs in high-volume assembly.
- Superior corrosion resistance provided by 410 Stainless Steel material, ensuring long-term reliability in demanding industrial environments.
- Secure, flush-mount finish achieved with the standard 82° flat head and Phillips drive, preventing snagging and providing a clean aesthetic.
- Robust thread-forming (BSD) action creates strong, durable threads in steel and sheet metal, reducing the risk of stripping and loosening under vibration.
- Optimized for 0.1" thick materials, delivering precise performance and consistent results in sheet metal and steel applications.
- Full compliance with RoHS 3 and REACH regulations, guaranteeing safety and environmental responsibility for your projects and supply chain.
Professional Applications & Engineering Value
These No. 8 self-drilling tapping screws are engineered to solve critical fastening challenges in steel, stainless steel, and sheet metal fabrication. The 410 Stainless Steel construction provides the necessary hardness and corrosion resistance for longevity, while the thread-forming BSD design ensures a tight, secure fit that resists vibrational loosening—a common failure point in machinery and enclosures. The 7/32" drill tip and specific geometry allow it to penetrate up to 0.1" thick materials efficiently, streamlining the assembly process by combining drilling and tapping into a single operation. This eliminates alignment errors from separate drilling steps, increases production speed, and reduces overall installed cost, making it an indispensable industrial fastener for HVAC, electrical enclosures, and metal framing.
Specification Summary & Compliance
This fastener features a No. 8 screw size with a 0.164" thread diameter and 18 TPI, fully threaded for maximum grip. The flat head is designed with a standard 82° countersink angle. Manufactured to BSD (Thread Forming) standards, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to strict environmental and safety guidelines for industrial components.
