S-90042A480 M6 x 25 mm ASME B18.3, DIN 912, ISO 4762 Sealing Socket Head Screws

Key Features & Benefits at a Glance

• Superior sealing performance with Viton® fluoroelastomer O-ring that prevents leaks in high-pressure systems up to 1500 psi
• Exceptional temperature resistance from -20° to 400°F, maintaining seal integrity in extreme thermal environments
• High tensile strength of 100,000 psi ensures reliable fastening under heavy mechanical loads
• Corrosion-resistant 18-8 stainless steel construction provides long-term durability in harsh industrial conditions
• Precision Class 6g thread fit guarantees smooth installation and secure mating with components
• Standard hex socket drive allows for easy installation with common 5mm hex tools in confined spaces
• Full thread engagement along the 25mm length enables maximum holding power across the entire fastener

Professional Applications & Engineering Value

This M6 socket head cap screw with Viton® O-ring sealing addresses critical challenges in high-pressure industrial applications where fluid containment and temperature extremes are common concerns. The combination of 18-8 stainless steel material and fully threaded M6x1mm coarse thread design provides both corrosion resistance and reliable fastening strength, while the integrated fluoroelastomer seal eliminates the need for additional sealing components. Engineers specify this metric hex socket screw for hydraulic systems, pneumatic equipment, and processing machinery where pressure ratings up to 1500 psi and temperature ranges from -20° to 400°F demand uncompromising sealing reliability. The standard socket head profile and 5mm hex drive facilitate maintenance in space-constrained environments, making it ideal for OEM and MRO applications across multiple industries.
