Professional Applications & Engineering Value

These No. 12 Phillips flat head tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and thread stripping. The thread forming technology displaces material rather than cutting it, resulting in stronger, vibration-resistant connections that maintain integrity under stress. Made from zinc-plated steel, they offer excellent durability against corrosion, making them ideal for HVAC systems, electronic enclosures, and automotive assemblies. The 82° countersink angle ensures a seamless fit, reducing the risk of surface damage and improving aesthetic appeal in finished products. With a right-hand thread direction and fully threaded design, they provide consistent clamping force, enhancing reliability in high-volume manufacturing and repair operations.

Specification Summary & Compliance

This product adheres to precise dimensional standards, including a thread diameter of 0.216" and 11 threads per inch, ensuring compatibility with industry requirements. The flat head profile and Phillips drive size No. 3 facilitate easy installation. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in regulated environments. Designed for sheet metal applications with a maximum drilling thickness of 0.025", these screws meet performance expectations for strength and reliability in various industrial settings.
