• Clean, flush installation with standard flat head profile and 82° countersink angle for smooth surface finish.
• Quick, reliable driving with Phillips No. 3 drive style that prevents cam-out and ensures consistent torque application.
• Precise dimensional accuracy with No. 12 screw size and 0.216" thread diameter for perfect fit in 3/16" pre-drilled holes.
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing practices.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger thread engagement than conventional fasteners. The fully threaded configuration ensures maximum pull-out resistance across the entire fastener length, critical for thin-gauge sheet metal applications where vibration and stress loads are common. With Phillips flat head drive system, these screws provide reliable, flush-mount fastening ideal for HVAC systems, electronic enclosures, and automotive panels where surface aesthetics matter. The combination of stainless steel material and precision thread forming technology solves common industry challenges of galvanic corrosion, thread stripping, and installation efficiency in high-volume production environments.

Specification Summary & Compliance

These Type A thread forming screws feature precise dimensional specifications including No. 12 screw size, 0.216" thread diameter, and 11 threads per inch for consistent performance. The manufacturing adheres to standard inch system measurements with proper head diameter (0.412") and length (3-1/2") tolerances. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures these fasteners meet international standards for restricted substances and chemical safety, making them suitable for global supply chain requirements and environmentally conscious manufacturing operations.
