Professional Applications & Engineering Value

These 316 stainless steel oval head tapping screws deliver exceptional performance in demanding sheet metal applications where corrosion resistance is critical. The thread forming design (A/AB type) creates precise mating threads in base materials without chip removal, eliminating contamination risks in sensitive environments. The fully threaded configuration with 11 TPI provides maximum thread engagement in thin-gauge materials up to 0.025" thickness, ensuring reliable fastening in HVAC systems, electronic enclosures, and marine equipment. The oval head profile offers a finished appearance while the Phillips drive facilitates efficient installation in production environments. Manufactured from premium 316 stainless steel, these screws maintain integrity in saltwater, chemical, and high-humidity conditions where ordinary fasteners would fail.

Specification Summary & Compliance

These No. 12 tapping screws feature a 0.216" thread diameter with 11 threads per inch and 3/4" length, manufactured to standard thread forming specifications for consistent performance. The oval head design includes a 0.412" diameter and 0.2" height with standard profile. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards ensures these fasteners meet international regulatory requirements for hazardous substance restrictions, making them suitable for global industrial applications and environmentally conscious manufacturing operations.
