Professional Applications & Engineering Value

These 316 stainless steel Phillips flat head tapping screws deliver exceptional performance in demanding sheet metal applications where corrosion resistance and structural integrity 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 A/AB tapping screw type with fully threaded shank ensures maximum material engagement, while the 82° countersink angle provides a clean, flush finish that meets aesthetic and safety requirements. Engineered for metalworking and construction environments, these screws solve common challenges of material fatigue, galvanic corrosion, and installation efficiency, making them ideal for HVAC systems, electrical enclosures, and industrial equipment assembly where reliable fastening is critical.

Specification Summary & Compliance

These No. 12 tapping screws feature precise inch system measurements including 0.216" thread diameter, 11 threads per inch, and 3/4" length with standard Class 2A thread tolerances. The flat head design with 0.412" head diameter and 0.132" head height ensures proper seating in prepared holes. Manufactured to industry standards for thread forming screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability for professional applications requiring 3/16" drill bit preparation.
