Professional Applications & Engineering Value
This M3 socket head cap screw is engineered to solve critical fastening challenges in demanding industrial environments. The zinc-flake-coated alloy steel construction provides exceptional corrosion resistance, making it ideal for machinery, automotive assemblies, and outdoor equipment exposed to moisture and chemicals. The Class 12.9 strength rating and Rockwell C37 hardness ensure it withstands extreme vibrational loads and tensile stresses without failure. The standard hex socket drive allows for high-torque installation in tight spaces, while the fully threaded M3 x 0.5mm coarse thread delivers rapid assembly and reliable clamping force. These metric hex socket screws are perfect for precision engineering applications where failure is not an option.
Specification Summary & Compliance
This socket head cap screw features precise M3 x 0.5mm coarse threads with Class 5g6g thread fit tolerance, ensuring consistent performance. Manufacturing complies with DIN 912 and ISO 4762 specifications for dimensional accuracy. The product meets ASTM B117 salt spray testing requirements for corrosion resistance and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no SVHC substances above threshold limits.
