Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and efficiency are paramount. The thread-forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in high-volume production. The Phillips flat head with standard profile ensures secure, flush mounting in panels and enclosures, while the 82° countersink angle provides optimal material engagement without deformation. The combination of fully threaded construction and right-hand thread direction delivers maximum pull-out resistance in thin-gauge materials up to 0.025" thickness, making these No. 10-12 screws ideal for HVAC systems, electrical cabinets, automotive components, and industrial machinery where vibration resistance and long-term performance are critical.

Specification Summary & Compliance

This tapping screw features precise inch system measurements with No. 10 screw size, 0.19" thread diameter, and 1" length. The thread-forming tapping method conforms to A/AB standards with 12 threads per inch and fully threaded shank. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance. The standard flat head profile with 82° countersink angle and No. 2 Phillips drive size provides consistent performance across sheet metal fastening applications.
