S-91290A640 M12 x 100 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and durability with Class 12.9 rating and 170,000 psi tensile strength, ideal for high-stress industrial applications
• Superior corrosion resistance provided by the black-oxide finish on alloy steel, extending service life in harsh environments
• Precise torque transmission through the 10mm hex drive socket head, ensuring secure fastening without stripping
• Reliable thread engagement with M12 coarse thread (1.75mm pitch) and Class 5g6g fit, facilitating quick assembly and vibration resistance
• Optimized weight distribution from the partially threaded design, reducing material usage while maintaining structural integrity
• Consistent performance compliance meeting DIN 912/ISO 4762 standards for dimensional accuracy and interchangeability
• Environmental and safety assurance through RoHS 3 and REACH compliance, supporting sustainable manufacturing practices

Professional Applications & Engineering Value

This M12 socket head cap screw delivers critical engineering solutions where high tensile strength and corrosion resistance are paramount. The black-oxide alloy steel construction prevents rust in humid or chemically aggressive settings, while the Rockwell C37 hardness ensures the fastener withstands repetitive loads without deformation. Its coarse metric thread (1.75mm pitch) enables rapid installation in machinery, automotive assemblies, and structural frameworks, reducing assembly time. The partially threaded shank concentrates strength where needed, minimizing stress concentration points. Complying with DIN 912/ISO 4762, these screws offer reliable performance in heavy-duty applications like industrial equipment, robotics, and construction projects, where failure is not an option.

Specification Summary & Compliance

Manufactured to precise Class 5g6g thread fit tolerances per ISO metric standards, ensuring consistent engagement. The screw adheres to DIN 912/ISO 4762 dimensional specifications for socket head profile, head diameter (18mm), and length (100mm). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing the absence of hazardous substances. The Class 12.9 strength rating and 170,000 psi tensile strength validate its suitability for critical, high-load environments.
