Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M6 socket head cap screws address critical challenges in machinery, automotive, and construction sectors. The black-oxide alloy steel construction combats rust and wear, while the Class 12.9 strength and coarse thread design prevent loosening under vibration and dynamic loads. With a partially threaded shank and standard socket head profile, they facilitate precise installation in confined spaces, reducing assembly time and enhancing structural integrity. Ideal for high-tensile bolting where metric coarse threads and corrosion resistance are paramount, these screws deliver consistent performance in demanding environments.
Specification Summary & Compliance
This product adheres to DIN 912 specifications with M6x1 mm coarse threads and a Class 5g6g thread fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory alignment. Manufactured to uphold 170,000 psi tensile strength and Rockwell C37 hardness, it supports rigorous industrial standards without compromise.
