S-92178A177 M6 x 16 mm ASTM F879M, ISO 7380 Sealing Tamper-Resistant Torx Stainless Steel Button Head Screws

Key Features & Benefits at a Glance

• Tamper-resistant T27 drive prevents unauthorized access in public or high-security installations
• Integrated Buna-N rubber O-ring creates reliable fluid/gas seals up to 1500 psi maximum pressure
• Passivated 18-8 stainless steel construction provides excellent corrosion resistance for harsh environments
• 100,000 psi tensile strength ensures structural integrity under heavy mechanical loads
• Wide temperature tolerance (-40° to 225°F) maintains performance across extreme operating conditions
• Class 6g thread fit guarantees precise engagement and vibration resistance
• Rounded button head profile offers smooth surface finish while requiring minimal clearance

Professional Applications & Engineering Value

These M6 metric screws with 1 mm coarse pitch threading deliver critical sealing performance for industrial equipment, machinery enclosures, and fluid handling systems. The passivated 18-8 stainless steel material combined with Buna-N rubber O-ring addresses corrosion and pressure containment challenges in chemical processing, marine, and outdoor applications. The tamper-resistant Torx drive provides security without compromising installation efficiency, while the fully threaded design ensures consistent clamping force across the entire fastener length. Engineered to prevent leaks and unauthorized tampering in critical assemblies.
