Professional Applications & Engineering Value

This M4 socket head cap screw delivers critical engineering value in demanding industrial settings where failure is not an option. Manufactured from zinc-flake-coated alloy steel, it addresses common challenges like corrosion in chemical processing or outdoor equipment, while the Class 12.9 strength rating prevents stripping under high vibrational loads in machinery and automotive assemblies. The coarse thread (M4x0.7mm) facilitates quick installation and robust holding power in metals and composites, reducing assembly time without sacrificing reliability. Ideal for precision metric fastening in robotics, aerospace subassemblies, and heavy-duty mechanical systems, this screw ensures long-term performance by combining material durability with exacting thread standards.

Specification Summary & Compliance

This product features a metric thread size M4x0.7mm with Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy for consistent performance. It complies with DIN 912 and ISO 4762 specifications for socket head cap screws, along with ASTM B117 testing for corrosion resistance. The screw is fully certified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use worldwide.
