Professional Applications & Engineering Value
These No. 10 tapping screws with Black-Oxide Steel construction are engineered specifically for sheet metal applications where vibration resistance and long-term reliability are critical. The thread forming design eliminates the need for separate tapping operations, creating strong, permanent threads that won't loosen under stress. The Phillips pan head provides a low-profile installation while the fully threaded configuration ensures maximum engagement in materials up to 0.025" thickness. This A/AB tapping screw type delivers exceptional performance in HVAC systems, electrical enclosures, automotive assemblies, and industrial equipment where secure metal-to-metal fastening is essential for structural integrity.
Specification Summary & Compliance
This No. 10 x 2-1/2" tapping screw features a 0.19" thread diameter with 12 threads per inch in right-hand thread configuration. Manufactured to precise dimensional standards with Class 2A thread tolerance for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. Designed for use with No. 21 drill bits (0.159" diameter) in sheet metal applications requiring maximum drilling thickness of 0.025".
