S-91290A556 M10 x 140 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 due to the black-oxide finish on alloy steel, extending service life in harsh environments.
• Precise and reliable fastening with M10 coarse thread (1.5mm pitch) and Class 5g6g thread fit, ensuring secure connections and easy assembly.
• High torque capability from the 8mm hex socket drive and standard socket head profile, allowing for efficient installation with standard tools.
• Optimized for partial threading (32mm min thread length on a 140mm body), providing flexibility for applications requiring unthreaded shank sections.
• Hardened to Rockwell C37 for maximum wear resistance and long-term performance under repetitive loads.
• Compliance with international standards including DIN 912/ISO 4762, RoHS 3, and REACH, ensuring safety and regulatory adherence for global use.

Professional Applications & Engineering Value

This M10 socket head cap screw is engineered to address critical challenges in demanding industrial settings, such as machinery assembly, automotive systems, and heavy equipment manufacturing. The black-oxide alloy steel construction combats rust and corrosion, reducing maintenance needs in humid or abrasive conditions. With a coarse thread (1.5mm pitch) and Class 5g6g thread fit, it offers quick installation and vibration resistance, minimizing loosening in dynamic applications. The partially threaded design allows for precise clamping where full threading isn't required, enhancing versatility in structural frameworks. Its high tensile strength and hardened surface make it a reliable choice for load-bearing components, ensuring operational safety and efficiency in industrial fasteners.

Specification Summary & Compliance

This screw adheres to precise dimensional standards with a thread fit of Class 5g6g and specifications meeting DIN 912 (identical to ISO 4762). It is manufactured from alloy steel with a black-oxide surface treatment and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability for industrial use.
