• Excellent holding power with fully threaded shank and 15 threads per inch, ensuring secure fastening in materials up to 0.025" thickness.
• Reliable drive engagement via Phillips No. 2 drive, minimizing cam-out and enhancing torque application during installation.
• Wide industrial compliance with RoHS 3 and REACH regulations, ensuring safety and environmental standards in global supply chains.
• Optimized pan head profile provides a low-profile, rounded finish for reduced snagging and improved aesthetics.
• Precision compatibility with No. 29 drill bits (0.136" diameter), facilitating accurate hole preparation for consistent performance.

Professional Applications & Engineering Value

Engineered for demanding sheet metal applications, these thread forming tapping screws address common industrial challenges like material fatigue and corrosion. The Black Oxide 18-8 Stainless Steel construction offers exceptional durability against moisture and chemicals, while the A/AB tapping screw type with right-hand threads creates strong, permanent threads in thin-gauge metals without requiring separate tapping operations. This design minimizes stress concentration and prevents stripping, making it ideal for HVAC systems, electronic enclosures, and automotive panels where reliable fastening and long-term performance are critical. The Phillips pan head ensures easy installation with standard tools, enhancing workflow efficiency in high-volume production environments.
