S-90042A184 M5 x 35 mm ASME B18.3, DIN 912, ISO 4762 Sealing Socket Head Screws

Key Features & Benefits at a Glance

• Superior Sealing Performance: Integrated silicone O-ring ensures reliable leak-proof connections, ideal for high-pressure applications up to 1500 psi.
• Exceptional Temperature Resistance: Withstands extreme conditions from -80° to 400° F, maintaining integrity in harsh industrial environments.
• High Tensile Strength & Durability: 100,000 psi tensile strength and Rockwell B85 hardness provide long-lasting, secure fastening under heavy loads.
• Precision Thread Fit: Class 6g thread tolerance ensures smooth installation and consistent engagement, reducing assembly time and errors.
• Corrosion-Resistant Material: 18-8 stainless steel construction offers excellent resistance to rust and corrosion, extending service life.
• Easy Installation with Hex Socket: 4 mm hex drive allows for high-torque application in confined spaces, minimizing tool slippage.
• Versatile Partially Threaded Design: Optimized for precise clamping where full threading isn't required, enhancing application flexibility.

Professional Applications & Engineering Value

This M5 socket head cap screw with a silicone O-ring seal is engineered to address critical sealing challenges in industrial settings. The 18-8 stainless steel material provides robust corrosion resistance, while the class 6g thread fit and 0.8 mm coarse pitch ensure reliable fastening in high-vibration environments like machinery, automotive assemblies, and hydraulic systems. The partially threaded design allows for precise unthreaded shank engagement, reducing stress concentrations and improving joint integrity. Ideal for applications requiring high-pressure sealing up to 1500 psi and temperature extremes from -80° to 400° F, this screw minimizes fluid or gas leakage risks, enhancing operational safety and efficiency in pumps, valves, and compressed air systems.
