Professional Applications & Engineering Value
These No. 10-12 x 2" zinc-plated steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The thread-forming A/AB tapping screw design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, permanent threads in metal substrates. The Phillips/Slotted drive system offers flexibility for various production environments, while the fully threaded configuration ensures maximum pull-out resistance. The zinc-plated steel construction provides reliable corrosion protection, making these industrial fasteners ideal for HVAC systems, electrical enclosures, automotive components, and machinery where vibration resistance and long-term reliability are critical.
Specification Summary & Compliance
This tapping screw features a No. 10-12 thread size with 12 threads per inch and 0.19" thread diameter, designed for use with No. 21 drill bits (0.159" diameter) in sheet metal up to 0.025" thickness. The right-hand thread direction and fully threaded configuration provide consistent fastening performance. Manufactured to industry standards for A/AB tapping screw types, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in global industrial markets.
