• Eliminates pre-drilling requirements with integrated drill tip that penetrates up to 0.09" thickness in steel and sheet metal
• Superior corrosion resistance thanks to 18-8 stainless steel construction for extended service life in demanding environments
• Stronger thread engagement through thread forming technology that creates secure, vibration-resistant fastenings
• Streamlined installation with Phillips No. 2 drive and oval head design for efficient assembly and professional finish
• Full-length threading ensures maximum grip and load distribution along the entire 1/2" length
• Regulatory compliance with RoHS 3 and REACH standards for safe, environmentally responsible manufacturing
• Precision engineering with standard BSD tapping screw specifications for reliable performance in metalworking applications

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws solve critical fastening challenges in steel and sheet metal fabrication by combining drilling and thread forming capabilities in a single operation. The thread forming technology displaces material rather than cutting it, creating stronger threads with improved resistance to vibration loosening. The No. 2 Phillips drive provides secure tool engagement during installation, while the oval head design offers a finished appearance that sits flush with the surface. With their fully threaded construction and precision drill tip, these screws eliminate the need for separate drilling operations, reducing assembly time and labor costs in industrial manufacturing, HVAC systems, and metal enclosure production.

Specification Summary & Compliance

These No. 6 x 1/2" tapping screws feature a 0.138" thread diameter with 20 threads per inch and standard BSD thread forming specifications. The oval head measures 0.262" in diameter with an 82° countersink angle for proper seating. Manufactured to industry standards for thread forming screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest requirements for hazardous substance restrictions in industrial applications.
