• Superior corrosion resistance thanks to the black-oxide finish on alloy steel, extending service life in demanding conditions.
• Precise torque application enabled by the 10mm hex drive and standard socket head profile, reducing installation time and tool wear.
• Optimized thread engagement with M12 coarse thread (1.75mm pitch) and Class 5g6g fit, providing excellent vibration resistance and easy alignment.
• Enhanced durability from Rockwell C37 hardness, maintaining performance under repetitive loads and harsh operational settings.
• Versatile partial threading for 36mm, allowing flexibility in clamping and adjustment while minimizing weight and material use.
• Global compliance assurance meeting DIN 912/ISO 4762 standards, RoHS 3, and REACH, ensuring safe and reliable use across international markets.

Professional Applications & Engineering Value

This M12 socket head cap screw is engineered to address critical challenges in heavy-duty machinery, automotive assembly, and construction equipment, where high tensile strength and fatigue resistance are paramount. The black-oxide alloy steel construction combats rust and wear, ideal for environments exposed to moisture or chemicals. With a coarse thread design (1.75mm pitch), it ensures rapid installation and robust holding power, reducing the risk of loosening under vibration. The partially threaded rod and precise Class 5g6g thread fit enable accurate positioning and load distribution, minimizing stress concentrations. These features make it a top choice for industrial socket screws in applications demanding reliability, such as engine mounts, structural frames, and precision tooling, where downtime from fastener failure is not an option.
