Professional Applications & Engineering Value
This M5 socket head cap screw delivers critical vibration resistance in demanding applications where permanent fastening is essential. The black-oxide alloy steel construction combined with the nylon patch thread locker creates a robust solution for machinery, automotive assemblies, and industrial equipment subjected to constant motion and thermal cycling. Engineers specify these metric socket screws for their reliable performance in high-stress environments, where the Class 5g6g thread fit ensures precise engagement and the fully threaded design provides maximum clamping force distribution. The combination of 170,000 psi tensile strength and Rockwell C37 hardness makes these fasteners ideal for critical joints in manufacturing equipment, robotics, and precision instruments where failure is not an option.
Specification Summary & Compliance
This socket head cap screw features M5 x 0.8mm coarse metric thread with Class 5g6g tolerance for precision fit, manufactured to DIN 912/ISO 4762 standards. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industries. With a 20mm length and fully threaded design, it provides consistent performance meeting international quality and safety requirements for industrial fastening applications.
