Professional Applications & Engineering Value

This Class 12.9 socket head cap screw is engineered for demanding industrial applications where failure is not an option. The zinc-flake-coated alloy steel construction provides excellent corrosion resistance, addressing common issues in machinery exposed to moisture or chemicals. With its M4 coarse thread and fully threaded design, it ensures rapid assembly and uniform stress distribution in tight spaces. The 3 mm hex drive allows for high torque application without stripping, making it ideal for precision equipment, automotive components, and heavy machinery where vibration resistance and reliability are critical. These metric socket head screws deliver consistent performance in high-stress environments while maintaining dimensional accuracy per DIN 912 specifications.

Specification Summary & Compliance

This socket head cap screw features M4 x 0.7 mm coarse threads with Class 5g6g tolerance, ensuring precise fit and interchangeability. Manufactured to DIN 912 standards with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. The Class 12.9 strength rating guarantees minimum tensile strength of 170,000 psi and Rockwell C37 hardness, meeting rigorous industrial requirements for high-strength fastening solutions.
