• Reliable, vibration-resistant hold in sheet metal up to 0.025" thick, ensuring secure fastening in dynamic applications.
• Broad compatibility with standard No. 21 drill bits (0.159" diameter), simplifying the preparation and installation process.
• Optimized for high-torque driving with a No. 2 Phillips pan head, providing a secure grip and reducing cam-out risk.
• Full-length threading for maximum engagement and pull-out strength across the entire 1" length.
• Compliance with major environmental and safety regulations including RoHS 3 and REACH, ensuring suitability for global supply chains.

Professional Applications & Engineering Value

This No. 10-12 thread forming screw is engineered specifically for sheet metal applications, where material integrity and joint reliability are paramount. The Black-Oxide Steel construction provides a durable barrier against oxidation, crucial for components exposed to humidity or varying temperatures. Its A/AB tapping screw type and thread forming method create strong, precise threads in pre-drilled holes without generating chips, eliminating contamination risks in sensitive assemblies like electrical enclosures, HVAC systems, and automotive panels. The combination of a Phillips pan head and fully threaded right-hand design ensures consistent clamp load and ease of use with common power tools, streamlining production lines and reducing installation errors.

Specification Summary & Compliance

This screw conforms to standard inch measurements with a thread diameter of 0.19" and 12 threads per inch. It is designed as a thread forming tapping screw (Type A/AB) for use with a No. 21 drill bit (0.159" diameter). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and health safety standards for industrial use.
