• Reliable performance in right-hand thread configuration with pointed tip for easy starting and alignment

Professional Applications & Engineering Value

These Black-Oxide Steel oval head Phillips tapping screws are specifically engineered for sheet metal applications where reliability and efficiency are paramount. The thread forming (A/AB type) design eliminates the need for separate tapping operations, creating strong, wear-resistant threads directly in the base material. This proves particularly valuable in high-volume manufacturing environments, reducing assembly time while providing vibration-resistant fastening. The combination of fully threaded construction and pointed tip design ensures quick starts and consistent penetration through metal sheets up to 0.025" thickness. The oval head profile with standard dimensions provides a clean, finished appearance while the Black-Oxide coating offers additional protection against environmental factors in industrial settings.

Specification Summary & Compliance

These No. 10-12 x 1-3/4" tapping screws feature precise Class 2A thread tolerances with 0.19" thread diameter and 12 threads per inch. Manufactured to A/AB thread forming standards with right-hand threading and fully threaded shank design. The screws maintain compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industry standards for restricted substances. The oval head configuration follows standard industrial profiles with 0.362" head diameter and 0.176" head height for consistent performance across applications.
