S-91290A223 M10 x 70 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance under extreme loads, reducing the risk of fastener failure in critical applications.
• Superior corrosion resistance from the black-oxide finish prolongs service life in harsh industrial environments, minimizing maintenance and replacement costs.
• High hardness (Rockwell C37) provides excellent wear resistance, maintaining thread integrity and drive engagement over repeated use.
• Precision Class 5g6g thread fit guarantees consistent assembly and secure fastening, reducing installation errors and improving joint reliability.
• Coarse M10 x 1.5mm thread enables quick installation and high resistance to vibration loosening, ideal for dynamic mechanical systems.
• 8mm hex drive design allows for high torque application with standard tools, ensuring tight clamping force without stripping the socket.
• Full compliance with DIN 912/ISO 4762 standards ensures interchangeability and quality consistency, meeting global engineering specifications.

Professional Applications & Engineering Value

These Class 12.9 metric socket head cap screws are engineered to address critical challenges in heavy-duty machinery, automotive assemblies, and precision equipment where high tensile strength and vibration resistance are paramount. The black-oxide alloy steel construction combats rust and oxidation in humid or chemically aggressive settings, while the coarse thread pitch enhances grip in soft materials and resists self-loosening under dynamic loads. With a fully threaded rod and standard socket head profile, they provide uniform stress distribution and easy access in confined spaces, making them ideal for high-performance industrial fastening that demands durability and precision alignment.

Specification Summary & Compliance

This M10 x 1.5mm socket head cap screw features a Class 5g6g thread fit per ISO metric standards, ensuring dimensional accuracy and compatibility. It adheres to DIN 912 / ISO 4762 manufacturing specifications for head geometry and drive style, and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of hazardous substances for safe use in global markets.
