• Precise 82° countersink angle provides flush mounting and clean professional finish in sheet metal applications
• Full threading design delivers maximum holding power along the entire screw length for enhanced joint security
• Optimized for 0.1875" drill bits with clear compatibility guidelines, simplifying preparation and reducing installation errors
• Right-hand thread direction with standard Phillips drive ensures familiar, straightforward installation using common tools
• Environmental compliance assurance with RoHS 3 and REACH regulations, meeting international standards for responsible manufacturing

Professional Applications & Engineering Value

These No. 12 Phillips flat head tapping screws are engineered specifically for sheet metal applications where reliability and efficiency are paramount. The zinc-plated steel construction provides essential corrosion protection in industrial settings, while the thread forming technology eliminates the need for separate tapping operations, significantly reducing assembly time and costs. The 82° countersink angle ensures a flush finish that maintains aerodynamic profiles and prevents snagging in machinery applications. With fully threaded design and 0.216" thread diameter, these fasteners distribute load evenly across the entire engagement length, preventing pull-out in thin sheet metal up to 0.025" thickness. The combination of A/AB tapping screw standards and Phillips drive makes these ideal for HVAC systems, electrical enclosures, and metal fabrication where consistent, reliable fastening is critical.

Specification Summary & Compliance

These tapping screws feature precise No. 12 screw size with 0.216" thread diameter and 11 threads per inch, manufactured to standard tolerances for consistent performance. The flat head profile with standard dimensions ensures proper seating in prepared holes. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to international environmental and safety standards for industrial fasteners.
