S-91290A466 M8 x 90 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Maximum load-bearing capacity with Class 12.9 strength rating and 170,000 psi tensile strength for critical applications
• Superior corrosion resistance through black-oxide coating that protects against rust in harsh environments
• Precise torque transmission via 6mm hex socket drive that prevents stripping and ensures secure fastening
• Optimized thread engagement with Class 5g6g thread fit and M8x1.25 coarse thread for reliable performance in vibration-prone settings
• Enhanced durability from Rockwell C37 hardness that maintains structural integrity under repeated stress
• Versatile partial threading allowing both threaded and unthreaded sections for flexible mounting solutions
• Global compliance assurance meeting DIN 912/ISO 4762 standards with RoHS 3 and REACH environmental regulations

Professional Applications & Engineering Value

These M8 socket head cap screws deliver exceptional engineering value in demanding industrial applications where failure is not an option. The black-oxide alloy steel construction provides superior corrosion resistance while maintaining the Class 12.9 strength rating required for heavy machinery, automotive assemblies, and precision equipment. The hex socket drive enables high-torque installation in confined spaces, while the coarse thread pitch (1.25mm) ensures rapid assembly and superior vibration resistance. With partial threading and 90mm length, these metric hex socket screws offer precise clamping force distribution, making them ideal for structural frameworks, manufacturing jigs, and high-stress mechanical systems where reliability and compliance with international standards are paramount.

Specification Summary & Compliance

This socket head cap screw features M8x1.25mm coarse threads with Class 5g6g thread fit tolerance, ensuring precise dimensional accuracy per ISO 4762 and DIN 912 specifications. The 90mm length includes 28mm minimum thread length with partially threaded design. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted substances. The mechanical properties exceed 170,000 psi tensile strength with Rockwell C37 hardness, validating the Class 12.9 performance rating for industrial fastening applications.
