Professional Applications & Engineering Value
This M4 socket head cap screw delivers exceptional value in applications where metal fasteners fail. The polypropylene plastic construction eliminates corrosion concerns in chemical processing, food equipment, and marine environments while providing electrical insulation. With its metric coarse thread and Class 6g thread fit, it ensures rapid assembly and reliable performance in plastic-to-plastic or plastic-to-metal joints. The hex socket drive allows for high torque application without stripping, making it ideal for industrial equipment, electronic enclosures, and automotive components where weight reduction and chemical resistance are critical. Its fully threaded design provides maximum holding power across the entire 12mm length.
Specification Summary & Compliance
This metric fastener features precise M4 x 0.7mm coarse threads with Class 6g tolerance per ISO standards. Manufactured to DIN 912 specifications with right-hand threading and standard socket head profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no hazardous substances. The polypropylene material meets UL 94 HB flammability rating for safety-critical applications.
