Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M12 socket head cap screws solve critical fastening challenges in heavy machinery, automotive assemblies, and precision equipment. The black-oxide alloy steel construction provides essential corrosion protection where lubricants or environmental factors threaten fastener integrity. With Class 12.9 strength rating and 170,000 psi tensile strength, they prevent joint failure in high-vibration environments while the standard hex drive ensures consistent torque application during maintenance cycles. The metric coarse threading (1.75mm pitch) facilitates rapid assembly in production lines while maintaining DIN 912/ISO 4762 compliance for interchangeable use in global manufacturing specifications.
Specification Summary & Compliance
Manufactured to Class 5g6g thread fit tolerance ensuring precision engagement with standard metric nuts. Fully compliant with DIN 912/ISO 4762 dimensional standards for socket head cap screws. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features 36mm minimum thread length on 220mm partially threaded shaft with right-hand coarse threading (M12 x 1.75mm).
