Professional Applications & Engineering Value

Engineered for high-stress industrial assemblies, these M12 socket head cap screws deliver critical vibration resistance where loosening under dynamic loads is a primary concern. The nylon patch thread locker technology eliminates the need for separate locking washers or adhesives, streamlining installation while providing reliable performance across a wide temperature range from -70° to 250° F. Manufactured from black-oxide alloy steel, these fasteners offer enhanced corrosion protection in challenging environments while maintaining 170,000 psi tensile strength for structural applications. The coarse metric threading with Class 5g6g tolerance ensures quick assembly with consistent clamping force, making them ideal for machinery, automotive components, and heavy equipment where DIN 912/ISO 4762 compliance is required.

Specification Summary & Compliance

This fully threaded metric screw features M12x1.75mm coarse threading with Class 5g6g thread fit per ISO standards. Manufacturing specifications conform to DIN 912 where identical to ISO 4762 for dimensional accuracy and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international substance restrictions. The 40mm length provides consistent thread engagement while the standard socket head profile with 10mm hex drive enables precise torque application.
