S-96144A297 M12 x 40 mm DIN 912 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 170,000 psi tensile strength for reliable performance in high-stress applications
• Superior corrosion resistance thanks to black-oxide coating that protects against rust and extends service life
• Precise torque transmission enabled by 10mm hex drive design that prevents stripping and ensures secure fastening
• Enhanced thread engagement through extra fine 1.25mm pitch for superior vibration resistance in dynamic environments
• Maximum material durability with Rockwell C37 hardness that maintains structural integrity under repeated use
• Full-threaded design providing consistent clamping force along the entire 40mm length for uniform load distribution
• Industry-standard compatibility with DIN 912 specifications ensuring reliable interchangeability and fit

Professional Applications & Engineering Value

This M12 socket head cap screw with extra fine thread configuration addresses critical engineering challenges in heavy machinery, automotive assemblies, and precision equipment. The Class 12.9 alloy steel construction combined with black-oxide surface treatment provides exceptional resistance to both mechanical stress and environmental corrosion, making it ideal for applications requiring long-term reliability in demanding conditions. The metric hex socket drive system ensures maximum torque transfer while minimizing the risk of tool slippage, particularly valuable in confined spaces where accessibility is limited. These fully threaded fasteners deliver uniform clamping force across the entire engagement length, preventing joint loosening in high-vibration industrial environments while maintaining precise alignment in critical assemblies.
