Professional Applications & Engineering Value

These No. 8-15 thread forming tapping screws deliver exceptional engineering value in sheet metal applications where reliable fastening is critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making these flat head screws ideal for HVAC systems, electronic enclosures, and automotive components exposed to moisture or chemicals. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger thread engagement through material displacement. With square drive compatibility, these screws prevent driver slippage during high-torque installation, ensuring consistent seating and reducing workplace injuries. The 82° countersink angle and standard flat head profile allow for flush mounting in precision assemblies, while the fully threaded configuration maximizes pull-out resistance in thin-gauge materials up to 0.025" thickness.

Specification Summary & Compliance

These thread forming screws feature precise No. 8-15 thread specifications with 0.164" thread diameter and 15 threads per inch, manufactured to industry standards for A/AB tapping screw types. The right-hand threaded design ensures standard installation compatibility, while the square drive No. 2 provides secure tool engagement. All dimensions maintain industrial tolerances for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental standards for hazardous substance restrictions and chemical safety in industrial applications.
