S-90042A191 M6 x 50 mm ASME B18.3, DIN 912, ISO 4762 Sealing Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh environments.
• Reliable sealing under extreme conditions thanks to the silicone rubber O-ring, which withstands pressures up to 1500 psi and temperatures from -80° to 400° F.
• High mechanical strength with 100,000 psi tensile strength and Rockwell B85 hardness, providing durability for demanding applications.
• Precise thread engagement with Class 6g thread fit and coarse 1 mm pitch, enabling quick assembly and secure fastening.
• Versatile installation through a standard hex socket (5 mm drive), allowing easy access in confined spaces with standard tools.
• Optimized load distribution from the partially threaded design and 24 mm minimum thread length, reducing stress concentration.
• Broad compatibility with maximum hole diameter of 6.655 mm, facilitating integration into various industrial setups.

Professional Applications & Engineering Value

This M6 socket head cap screw is engineered to address critical challenges in industrial sealing and fastening. Made from 18-8 Stainless Steel, it resists corrosion in moist or chemical-exposed environments, while the silicone rubber O-ring ensures a tight seal against fluids and gases under high pressure (up to 1500 psi). The coarse metric thread with Class 6g tolerance allows for rapid, vibration-resistant assembly in machinery, automotive, and plumbing systems. Its partially threaded profile minimizes thread damage and distributes loads evenly, enhancing joint integrity. Ideal for applications requiring temperature resistance from -80° to 400° F, this screw provides a dependable solution for OEMs and maintenance teams seeking compliance with international standards.

Specification Summary & Compliance

This product features a Class 6g thread fit per metric standards, ensuring dimensional accuracy for consistent performance. It meets ASME B18.3, DIN 912, and ISO 4762 specifications for socket head cap screws, guaranteeing interoperability and safety. Additionally, it is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, supporting environmental and health regulations in global supply chains.
