Professional Applications & Engineering Value
These No. 12 Phillips tapping screws are specifically engineered for sheet metal applications where reliability and efficiency are paramount. The thread forming technology eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't loosen under stress. The Black-Oxide Steel construction provides essential corrosion protection in industrial environments, while the fully threaded design with pointed tip ensures quick starts and maximum thread engagement. Ideal for HVAC systems, electrical enclosures, and metal fabrication, these A/AB tapping screws deliver consistent performance with their standardized 3/16" drill bit requirement, streamlining your assembly process and reducing total installation costs.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.216" thread diameter and 11 threads per inch, these screws feature Class 2A thread tolerances for reliable fit. The thread forming (Type A/AB) design complies with industry standards for sheet metal fastening. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global manufacturing applications.
