Professional Applications & Engineering Value
These M12 socket head cap screws deliver critical engineering solutions where high tensile strength and precision threading are paramount. The black-oxide alloy steel construction provides essential corrosion protection for machinery, automotive assemblies, and industrial equipment exposed to demanding conditions. The extra fine 1.25mm pitch metric thread offers superior clamping force distribution, while the partially threaded design concentrates engagement where needed most. With Class 12.9 strength rating and Rockwell C37 hardness, these fasteners withstand extreme vibration and shock loads in heavy machinery, construction equipment, and precision manufacturing applications where failure is not an option.
Specification Summary & Compliance
This socket head cap screw features M12 x 1.25mm extra fine threading with Class 5g6g thread fit tolerance, ensuring precise engagement and reliable performance. Manufactured to DIN 912 and ISO 21269 standards with 70mm total length and 36mm minimum thread length. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting current environmental safety regulations for industrial use across global markets.
