S-91290A382 M3.5 x 10 mm ASTM A574M, DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 170,000 psi tensile strength and Class 12.9 rating for reliable performance in high-stress applications
• Superior corrosion resistance provided by the black-oxide finish on alloy steel, extending service life in harsh industrial environments
• Precise torque transmission enabled by the 2.5mm hex socket drive, minimizing tool slippage and ensuring secure fastening
• Optimized thread engagement through M3.5 coarse threading (0.6mm pitch) with Class 6g tolerance for quick assembly and vibration resistance
• Maximum material hardness at Rockwell C37, providing excellent wear resistance and maintaining thread integrity under repeated use
• Full thread coverage along the 10mm length for consistent clamping force distribution across the entire fastener
• Global compliance assurance meeting DIN 912, ISO 4762, and ASTM A574M specifications for international project compatibility

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these high-strength socket head cap screws deliver critical performance where failure is not an option. The black-oxide alloy steel construction provides superior corrosion protection while maintaining the Class 12.9 strength rating essential for heavy machinery, automotive assemblies, and precision equipment. The M3.5 metric coarse threading with 0.6mm pitch ensures rapid installation and superior vibration resistance in dynamic environments. The 2.5mm hex drive socket allows for high-torque application without stripping, while the fully threaded design maximizes contact surface for uniform stress distribution. These socket head cap screws are particularly valuable in confined spaces where their low-profile head and reliable fastening capability prevent joint failure in critical structural applications.
