Professional Applications & Engineering Value

This M4 socket head cap screw delivers critical engineering advantages in demanding applications where corrosion resistance and mechanical reliability are paramount. Manufactured from 316 stainless steel, it withstands aggressive environments including marine, chemical processing, and food equipment where oxidation or chemical degradation would compromise standard fasteners. The cold worked fabrication enhances grain structure, providing consistent tensile strength (110,000 psi) that prevents failure under dynamic loads or vibration. With its fully threaded M4 x 0.7mm coarse thread profile and Class 6g fit, installation torque is efficiently transferred into clamping force without stripping. The hex socket drive allows high torque application in space-constrained assemblies, making it ideal for machinery, precision instruments, and structural frames requiring flush mounting and reliable disassembly.

Specification Summary & Compliance

This precision metric socket head screw features M4 x 0.7mm coarse right-hand threads with Class 6g thread fit per ISO metric standards, ensuring dimensional accuracy across mating components. Manufacturing and quality control adhere to DIN 912 / ISO 4762 specifications for socket head cap screws, guaranteeing consistent head dimensions (7 mm diameter, 4 mm height) and drive compatibility. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances above threshold limits for industrial and international use.
