Professional Applications & Engineering Value
These Class 12.9 socket head cap screws deliver critical engineering solutions for heavy machinery, automotive assemblies, and industrial equipment where high tensile strength and vibration resistance are paramount. The black-oxide alloy steel construction provides superior protection against rust and corrosion in demanding environments, while the coarse pitch metric threading (M12x1.75mm) ensures rapid assembly and reliable performance under dynamic loads. The partially threaded design offers precise clamping force control, making these DIN 912/ISO 4762 compliant screws ideal for applications requiring both threaded engagement and smooth shank guidance. With their 10mm hex drive and standardized socket head profile, they enable efficient installation in confined spaces common in industrial maintenance and manufacturing operations.
Specification Summary & Compliance
This socket head cap screw features precise Class 5g6g thread fit tolerance with M12x1.75mm coarse pitch threading and 36mm minimum thread length on a 70mm overall length. Manufactured to DIN 912/ISO 4762 specifications with Class 12.9 strength rating and Rockwell C37 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global market acceptance.
