S-90042A275 M6 x 10 mm ASME B18.3, DIN 912, ISO 4762 Sealing Socket Head Screws

Key Features & Benefits at a Glance

• Superior Sealing Performance: Integrated Buna-N rubber O-ring ensures reliable leak-proof sealing in high-pressure applications up to 1500 psi, reducing maintenance and downtime.
• Exceptional Corrosion Resistance: 18-8 stainless steel construction provides excellent durability against rust and chemical exposure, ideal for harsh industrial environments.
• High Tensile Strength & Durability: With 100,000 psi tensile strength and Rockwell B85 hardness, this screw maintains structural integrity under heavy loads and vibration.
• Precision Thread Fit: Class 6g thread ensures consistent, accurate engagement with mating components, minimizing cross-threading and assembly errors.
• Broad Temperature Compatibility: O-ring functions effectively from -40° to 225° F, making it suitable for both low-temperature and high-heat applications.
• Easy Installation with Hex Drive: 5 mm hex socket drive allows for secure, high-torque installation using standard tools, speeding up assembly processes.
• Full Thread Engagement: Fully threaded design maximizes holding power and distributes stress evenly along the entire length for enhanced joint reliability.

Professional Applications & Engineering Value

This M6 metric socket head cap screw is engineered to address critical sealing and fastening challenges in demanding industrial settings. The combination of 18-8 stainless steel and a Buna-N rubber O-ring provides a robust solution for applications where fluid or gas containment is essential, such as in hydraulic systems, pneumatic equipment, and machinery enclosures. The coarse 1 mm pitch thread and Class 6g thread fit ensure quick, secure assembly while resisting loosening under dynamic loads. Its fully threaded M6 x 10 mm design offers versatile mounting options in tight spaces, commonly used in automotive, manufacturing, and electronics industries where corrosion resistance and high-pressure sealing are paramount. By integrating sealing directly into the fastener, it eliminates the need for additional gaskets, simplifying design and reducing component count.
