Professional Applications & Engineering Value
This M5 socket head cap screw with black-oxide alloy steel construction addresses critical engineering challenges in heavy-duty machinery, automotive, and precision equipment. The fully threaded design and coarse 0.8mm pitch enable rapid assembly and strong holding power, while the integrated flat washer eliminates the need for separate components, reducing installation time and preventing loosening under vibration. Its high tensile strength and corrosion-resistant finish make it ideal for applications requiring durability in exposed or high-load environments, such as industrial robots, conveyor systems, and structural frameworks. By combining metric coarse thread reliability with robust material properties, this fastener delivers consistent performance where precision and longevity are paramount.
Specification Summary & Compliance
This screw features a metric M5 x 0.8mm thread with Class 6g tolerance for precise fit, and is manufactured to ASTM A574 specifications for high-strength socket head cap screws. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards. Dimensions include a 12mm length, 8.72mm head diameter, and 15mm washer OD, supporting reliable use in standardized industrial assemblies.
