S-92178A179 M6 x 25 mm ASTM F879M, ISO 7380 Sealing Tamper-Resistant Torx Stainless Steel Button Head Screws

Key Features & Benefits at a Glance

• Tamper-resistant T27 Torx drive prevents unauthorized access, enhancing security in public or sensitive installations
• Integrated Buna-N rubber O-ring creates a reliable seal against fluids and contaminants, withstanding pressures up to 1500 psi
• Passivated 18-8 stainless steel construction provides excellent corrosion resistance for long-term durability in harsh environments
• High tensile strength of 100,000 psi ensures reliable fastening under mechanical stress and vibration
• Metric coarse threading with Class 6g fit offers quick installation and secure engagement in various materials
• Rounded button head design presents a smooth, low-profile finish that reduces snagging and improves safety
• Broad temperature compatibility (-40° to 225° F) maintains performance across diverse operating conditions

Professional Applications & Engineering Value

This M6 metric screw with 1 mm pitch coarse threading and tamper-resistant Torx drive is engineered to address critical challenges in industrial assembly and maintenance. The combination of passivated 18-8 stainless steel and Buna-N rubber O-ring creates a dual-purpose fastener that simultaneously provides security against tampering and effective sealing against moisture, dust, and pressure variations. This makes it ideal for enclosure panels, fluid systems, and outdoor equipment where both vandal resistance and environmental protection are paramount. The fully threaded design with Class 6g thread fit ensures consistent engagement depth and clamping force, while the rounded button head minimizes protrusion hazards in high-traffic areas. These features collectively deliver reliable performance in manufacturing, transportation, and infrastructure applications requiring secure, sealed fastening solutions.

Specification Summary & Compliance
