Professional Applications & Engineering Value

These black-oxide steel tapping screws are specifically engineered for sheet metal applications where reliable fastening and corrosion resistance are critical. The thread forming technology eliminates the need for pre-tapped holes, creating strong, vibration-resistant threads that won't loosen under stress. The Phillips pan head design provides a flush finish while the No. 2 drive size ensures compatibility with standard industrial tools. With 12 threads per inch and full threading, these screws distribute load evenly across the entire fastener length, preventing material distortion in thin-gauge metals. The combination of black-oxide surface treatment and steel construction offers exceptional durability in manufacturing, HVAC, electrical enclosures, and automotive assembly applications where environmental factors and mechanical stresses are concerns.

Specification Summary & Compliance

This No. 10-12 x 1-3/4" tapping screw features precise 0.19" thread diameter with 12 threads per inch and Class 2A thread tolerances for consistent performance. The A/AB thread forming type complies with industry standards for sheet metal fastening applications. Manufactured to work with No. 21 drill bit (0.159" diameter) for optimal hole preparation. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
