Professional Applications & Engineering Value
This M20 socket head cap screw is engineered for heavy-duty industrial applications where high tensile strength and corrosion resistance are critical. Made from Class 12.9 alloy steel with a black-oxide coating, it effectively combats rust and wear in environments like machinery, automotive assemblies, and construction equipment. The partially threaded design and coarse metric thread (M20 x 2.5mm) provide reliable grip and ease of adjustment, reducing installation time and minimizing vibration-induced failures. With a 17mm hex drive and 30mm head diameter, it offers superior torque transmission, making it ideal for high-stress scenarios. This screw addresses common engineering challenges such as joint integrity and longevity, ensuring optimal performance in industrial fastening systems.
Specification Summary & Compliance
This product features precise Class 5g6g thread fit and metric coarse threading (M20 x 2.5mm) with a minimum thread length of 52mm, ensuring accurate and secure connections. It complies with DIN 912 standards for dimensional consistency and performance. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its environmental and safety adherence for global industrial use.
