Professional Applications & Engineering Value
This No. 8-18 tapping screw delivers exceptional engineering value in sheet metal fabrication and assembly operations. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, while the Type B thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs. The flat head with 82° countersink angle ensures a clean, flush finish that prevents snagging and maintains aerodynamic surfaces. With its fully threaded configuration and right-hand thread direction, this industrial fastener maintains consistent clamping force across the entire joint, preventing loosening under vibration and thermal cycling common in metal enclosures, HVAC systems, and electronic chassis applications.
Specification Summary & Compliance
This tapping screw features precision No. 8-18 thread with 0.164" diameter and 18 threads per inch, manufactured to standard Type B thread forming specifications. The flat head design includes an undercut profile for improved seating and a head diameter of 0.312" with 0.07" height. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial and commercial applications worldwide.
