• Regulatory compliance meeting RoHS 3 and REACH standards for safe use across industrial applications

Professional Applications & Engineering Value

These No. 8 hex head tapping screws deliver exceptional engineering value through their 410 Stainless Steel composition and thread forming technology. The integrated drilling tip with 0.098" maximum drilling thickness capability eliminates the need for separate drilling operations, significantly reducing installation time and labor costs in steel, stainless steel, and sheet metal applications. The flanged design provides superior clamping force distribution, preventing material deformation while the fully threaded configuration ensures maximum engagement strength. These self-tapping screws are engineered to create precise, durable threads in base materials, offering reliable performance in HVAC systems, electrical enclosures, automotive assemblies, and industrial equipment where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.164" thread diameter and 18 TPI thread pitch, these thread forming screws feature a 3/4" length and 0.348" flange diameter for consistent performance. The external hex drive and right-hand threading ensure compatibility with standard installation tools. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and material restrictions adherence for industrial applications requiring certified components.
