• Effortless installation thanks to the pointed tip and thread-forming design, reducing assembly time and tool wear.
• Maximum holding power in sheet metal applications with a fully threaded shank and 16 threads per inch for secure, vibration-resistant fastening.
• Wide compatibility with standard No. 2 Phillips drive tools, enabling quick and reliable tightening without slippage.
• Durable pan head design provides a low-profile, rounded finish that resists snagging and offers a clean appearance.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries.
• Precision-engineered dimensions like 0.151" thread diameter and 1/2" length for consistent fit in pre-drilled No. 30 holes.

Professional Applications & Engineering Value

This zinc-plated steel tapping screw is specifically designed for sheet metal fastening, addressing common challenges such as material fatigue and loosening under stress. The thread-forming A/AB type technology creates strong, permanent threads in metal without pre-tapping, reducing installation steps and minimizing the risk of strip-out. With a Phillips pan head and fully threaded body, it ensures even load distribution and high clamp force, making it ideal for HVAC systems, automotive assemblies, and electronic enclosures where reliability is critical. The pointed tip facilitates quick alignment, while the corrosion-resistant coating extends service life in harsh conditions, delivering consistent performance for industrial metal fasteners.

Specification Summary & Compliance
