S-90035A143 M5 x 18 mm DIN 912, ISO 4762, SAE AMS5731, SAE AMS5737 High-Strength A286 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength-to-weight ratio with 160,000 psi tensile strength and 120,000 psi yield strength for reliable performance in high-stress applications
• Superior corrosion resistance through A286 stainless steel construction and passivated finish, ensuring longevity in harsh industrial environments
• Precision thread engagement with Class 6g metric coarse threads (0.8mm pitch) providing secure fastening and vibration resistance
• Optimized drive efficiency featuring a standard 4mm hex socket for high torque application and reduced stripping risk
• Enhanced thermal stability maintaining mechanical properties at elevated temperatures due to A286 material characteristics
• Global compliance assurance meeting DIN 912/ISO 4762 standards and SAE AMS specifications for consistent quality across international projects
• Environmental responsibility with RoHS 3 and REACH compliance, supporting sustainable manufacturing initiatives

Professional Applications & Engineering Value

This M5 socket head cap screw delivers critical performance where standard fasteners fail. The A286 stainless steel composition provides exceptional creep resistance at temperatures up to 700°C, making it ideal for aerospace components, turbine assemblies, and high-temperature industrial equipment. The passivated finish creates a protective oxide layer that prevents galvanic corrosion when mating with dissimilar metals. With its fully threaded design and Class 6g thread fit, engineers achieve uniform clamping force distribution across the entire 18mm length, eliminating stress concentration points. The 4mm hex drive accommodates high torque values without cam-out, ensuring reliable installation in confined spaces common in machinery and automotive applications.

Specification Summary & Compliance
