Professional Applications & Engineering Value

These 316 stainless steel Phillips oval head tapping screws are engineered specifically for demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the need for pre-tapped holes while creating stronger, more vibration-resistant connections by displacing material rather than removing it. This design prevents metal shavings in sensitive equipment and provides superior pull-out resistance. The combination of fully threaded design and A/AB screw type ensures maximum thread engagement in materials up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and industrial machinery where reliable fastening is critical. The oval head profile offers both aesthetic appeal and functional countersinking capability.

Specification Summary & Compliance

These No. 12 x 2-1/2" tapping screws feature a 0.216" thread diameter with 11 threads per inch and comply with standard thread forming specifications for A/AB type screws. The manufacturing process ensures precise dimensional accuracy with standard oval head profile and 82° countersink angle compatibility. These screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
