S-98903A209 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring longevity in demanding industrial environments
• Effortless installation and secure fastening through thread forming design that creates strong, reliable threads in sheet metal without pre-tapping
• Clean, flush finish achieved with undercut flat head and 82° countersink angle, preventing surface protrusion and snagging hazards
• Optimized driving efficiency with Phillips No. 2 drive, providing excellent torque transfer and reducing cam-out during installation
• Maximum material penetration using pointed tip and fully threaded shank, delivering superior holding power in thin sheet metal applications
• Precision dimensional compliance with standard inch measurements (No. 6 size, 18 TPI) ensuring consistent performance and interchangeability
• Environmental regulation compliance meeting RoHS 3 and REACH standards for safe, sustainable industrial use

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and reliable fastening are critical. The thread forming design eliminates the need for pre-tapped holes, creating strong internal threads that resist vibration loosening and pull-out forces in thin materials. The undercut flat head profile with 82° countersink ensures a flush installation that prevents interference in tight assemblies while maintaining structural integrity. With Phillips No. 2 drive compatibility, these screws provide efficient installation using standard industrial tools, reducing assembly time and improving production efficiency in HVAC systems, electronic enclosures, and metal fabrication projects where maximum holding power in limited material thickness is essential.

Specification Summary & Compliance

These No. 6 x 3/4" tapping screws feature standard inch dimensions with 0.138" thread diameter, 18 TPI thread pitch, and fully threaded design for maximum engagement. Manufactured to industry standards for Type A thread forming screws with right-hand threading and pointed tip for optimal penetration. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial compliance requirements for hazardous substance restrictions and chemical safety standards.
