Professional Applications & Engineering Value

These black-oxide steel tapping screws are engineered specifically for sheet metal applications where reliable fastening and corrosion resistance are critical. The thread forming design eliminates the need for separate tapping operations, creating strong internal threads that resist loosening under vibration. The Phillips drive system with No. 3 size ensures efficient power transfer during installation, while the fully threaded configuration with pointed tip facilitates quick starts and consistent penetration. Ideal for HVAC systems, electrical enclosures, and automotive panels, these A/AB type screws provide exceptional pull-out strength and durability in thin-gauge materials up to 0.025" thickness, making them essential for high-volume manufacturing environments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.242" thread diameter and 10 threads per inch specification. Features Class 2A thread tolerance for consistent performance and compatibility with standard 5.5mm drill bits. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The thread forming tapping method follows industry-standard A/AB specifications for reliable performance in sheet metal applications.
