Professional Applications & Engineering Value
These M4 socket head cap screws deliver critical reliability in demanding industrial settings. The blue-dyed zinc-plated alloy steel construction combats corrosion in moisture-prone environments, while the Class 12.9 strength rating and 170,000 psi tensile strength prevent failure under extreme vibration or tension. The fully threaded design and coarse metric thread (0.7 mm pitch) enable rapid installation and robust clamping force in metals, plastics, and composites. Commonly used in machinery, automotive assemblies, and precision equipment, these hex drive screws with a 3 mm drive size offer engineers a trusted solution for high-performance fastening applications where precision and longevity are paramount.
Specification Summary & Compliance
This socket head cap screw features M4 x 0.7 mm coarse threads with Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy. It is manufactured to meet DIN 912/ISO 4762 specifications for socket head fasteners, guaranteeing consistent quality and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial use.
