• Reliable drive engagement provided by the Phillips No. 2 drive, ensuring secure torque transmission and reducing cam-out risks during installation.
• Low-profile pan head design offers a standard rounded profile for a finished appearance while maintaining good bearing surface.
• Precision dimensional accuracy with consistent No. 10-12 thread pitch and 1/2" length for reliable performance and interchangeability.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safety and regulatory acceptance in international markets.

Professional Applications & Engineering Value

This Black Oxide 18-8 Stainless Steel tapping screw is engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion. The thread forming (Type A/AB) design displaces material to create robust internal threads, eliminating the need for separate tapping operations and reducing assembly steps. The fully threaded shank and pointed tip ensure rapid penetration and uniform load distribution, preventing loosening under vibration. Its Phillips drive facilitates efficient installation with standard tools, making it ideal for HVAC systems, electronic enclosures, and automotive panels where durability and regulatory compliance are critical.

Specification Summary & Compliance

This screw features a No. 10-12 thread with a 0.19" diameter and 12 threads per inch, conforming to standard inch measurements for thread forming applications. The pan head has a diameter of 0.373" and height of 0.133", designed for a flush fit. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances. Recommended for use with a No. 21 drill bit (0.159" diameter) for optimal performance in sheet metal up to 0.025" thickness.
