Key Features & Benefits at a Glance

  • Enhanced corrosion resistance with 410 stainless steel material, ideal for harsh industrial environments and extended service life.
  • Superior self-drilling efficiency with a No. 3 drill tip, enabling quick installation in steel, stainless steel, and sheet metal up to 0.187" thick.
  • Secure, flush-mount fastening thanks to the standard flat head and 82° countersink angle, preventing snagging and ensuring a smooth surface finish.
  • Reliable thread-forming performance with BSD type and fully threaded design, creating strong, vibration-resistant threads without pre-tapping.
  • Effortless installation and removal with Phillips No. 3 drive, providing a common, accessible tool interface for maintenance and assembly.
  • Consistent dimensional accuracy with a No. 12 screw size, 0.216" thread diameter, and 14 threads per inch, ensuring precise fits and repeatable results.
  • Compliance with environmental standards, meeting RoHS 3 and REACH regulations for safe, sustainable use in global supply chains.

Professional Applications & Engineering Value

These No. 12 tapping screws are engineered to address common challenges in metalworking and fabrication, such as time-consuming pre-drilling and thread stripping. Made from 410 stainless steel, they offer excellent strength and corrosion resistance, making them suitable for demanding applications in steel, stainless steel, and sheet metal assemblies. The thread-forming design with BSD type and fully threaded shank ensures high clamp load and vibration resistance, reducing the need for additional locking hardware. The integrated drilling tip and flat head with an 82° countersink angle allow for rapid, flush installations, streamlining production lines and minimizing labor costs in industrial settings like HVAC, automotive, and machinery enclosures.

Specification Summary & Compliance

This product adheres to standard inch measurements with a screw size of No. 12, thread diameter of 0.216", and length of 3/4". It features a right-hand thread with approximately 14 threads per inch and is fully threaded for consistent engagement. The flat head profile and Phillips No. 3 drive comply with common industrial specifications. All manufacturing processes and materials are in full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and reliability for professional use.
