Professional Applications & Engineering Value

These 316 stainless steel Phillips flat head tapping screws deliver exceptional value in sheet metal fabrication and industrial assembly applications. The thread forming design eliminates the need for separate tapping operations, creating strong, strip-resistant threads while minimizing material stress. The fully threaded configuration provides maximum engagement in materials up to 0.025" thickness, ensuring reliable fastening in challenging thin-section applications. The combination of 316 stainless steel material and A/AB thread standard offers superior performance in corrosive environments including marine, chemical processing, and outdoor equipment. The 82° countersink angle and flat head profile create clean, flush installations that resist vibration loosening while maintaining structural integrity in demanding industrial settings.

Specification Summary & Compliance

These No. 8 x 1" tapping screws feature precision 0.164" thread diameter with approximately 15 threads per inch, manufactured to industry standards for consistent performance. The thread forming tapping method and right-hand thread direction ensure proper installation with recommended No. 29 drill bit (0.136" diameter). All components comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental responsibility and material safety for industrial applications worldwide.
