S-90198A446 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications
• Superior holding power through thread forming design that displaces material rather than cutting it, creating stronger, vibration-resistant connections
• Clean, flush installation with standard 82° countersink angle and flat head design for smooth surface finishes in sheet metal assemblies
• Optimized for thin materials with maximum drilling thickness of 0.025", perfect for precision sheet metal fabrication
• Reliable driving performance with No. 2 Phillips drive that provides secure tool engagement and reduces cam-out incidents
• Full threading coverage along the 2-1/2" length ensures maximum grip and load distribution across the entire fastener
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

These 316 stainless steel tapping screws deliver exceptional value in demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design (A/AB type) eliminates chip formation during installation, preventing contamination in sensitive equipment while creating stronger, more reliable joints through material displacement. The combination of fully threaded construction and right-hand threading provides superior pull-out resistance in thin-gauge materials up to 0.025" thickness. The standard 82° countersink angle ensures flush mounting without protrusion, while the No. 2 Phillips drive offers familiar, efficient installation for production environments. These industrial-grade tapping screws solve critical challenges in HVAC systems, electronic enclosures, and architectural metalwork where vibration resistance and long-term durability are essential.
