Key Features & Benefits at a Glance
- Eliminates pre-drilling with integrated No. 3 drill tip, saving significant labor time and cost in aluminum and sheet metal assembly.
- Superior corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
- Optimized for high-strength fastening in materials up to 0.175" thick, providing secure, vibration-resistant joints.
- Streamlined installation with Phillips flat head design and standard 82° countersink, enabling flush finishes and easy driver engagement.
- Consistent thread formation through thread-forming BSD design, reducing material stress and improving pull-out resistance.
- Full-threaded shank maximizes grip length and load distribution across the entire fastened material thickness.
- Compliance with global environmental standards (RoHS 3 and REACH) ensures safe, sustainable use in regulated industries.
Professional Applications & Engineering Value
These self-drilling tapping screws are precision-engineered to address common challenges in aluminum and sheet metal fabrication, where speed and joint integrity are critical. The 18-8 stainless steel material provides excellent resistance to oxidation and chemical exposure, extending service life in outdoor or corrosive settings. The thread-forming BSD design cold-forms mating threads as it drives, minimizing chip generation and preventing loosening under dynamic loads. Combined with the fully threaded shank and No. 3 drill tip, these screws deliver rapid penetration and high clamp force, reducing assembly time while maintaining structural stability in HVAC, enclosures, and metal framing applications.
Specification Summary & Compliance
This No. 14 screw features a 0.242" thread diameter with 14 threads per inch and right-hand threading. The flat head with 82° countersink angle ensures a seamless finish. Manufactured to BSD tapping screw standards for thread-forming applications, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to restricted substance guidelines for industrial safety and environmental responsibility.
