Key Features & Benefits at a Glance
- Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding industrial environments
- Efficient self-drilling capability eliminates pre-drilling requirements, saving significant installation time and labor costs
- Excellent thread-forming design creates strong, permanent threads in steel, stainless steel, and sheet metal applications
- Secure square drive system provides superior torque transmission and reduces cam-out during installation
- Optimized drill tip geometry (No. 2 tip) penetrates up to 0.09" thickness with consistent drilling performance
- Full threading along 1¼" length ensures maximum grip strength and uniform load distribution
- Comprehensive regulatory compliance meets RoHS 3 and REACH standards for global industrial applications
Professional Applications & Engineering Value
These No. 6 self-drilling tapping screws deliver exceptional engineering value through their 410 stainless steel composition and advanced thread forming design. The combination of BSD tapping screw technology and No. 2 drill tip addresses critical installation challenges in steel, stainless steel, and sheet metal assemblies by eliminating separate drilling operations. The 20 TPI right-hand thread configuration ensures secure fastening in thin materials while the pan head with square drive provides reliable torque transmission without stripping. This engineering solution significantly reduces assembly time while maintaining structural integrity in HVAC, metal fabrication, and industrial equipment applications where vibration resistance and corrosion protection are paramount.
Specification Summary & Compliance
These thread forming screws feature precise dimensional specifications including 0.138" thread diameter, 20 TPI thread pitch, and 1¼" fully threaded length. Manufactured to BSD tapping screw standards with standard pan head profile and No. 1 square drive. The product demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and suitability for global industrial markets. The self-drilling design incorporates a No. 2 drill tip with 9/64" tip length capable of penetrating materials up to 0.09" maximum thickness.
