• High-strength performance with 70,000 psi tensile strength and Rockwell B83 hardness for demanding mechanical applications.
• Secure, tamper-resistant fastening via the internal hex socket drive, providing a clean profile and high torque capability.
• Easy assembly and disassembly with coarse M5x0.8 thread and Class 5g6g fit, reducing cross-threading risks.
• Guaranteed dimensional consistency and interchangeability by conforming to the international ISO 7379 standard.
• Safe for sensitive applications with full compliance to RoHS 3 and REACH environmental regulations.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to provide a robust and precise locating pin and bearing surface in assemblies where components must rotate or align accurately. The 18-8 stainless steel material offers excellent resistance to oxidation and chemical exposure, making it suitable for automotive, machinery, and electronics applications. The 18mm shoulder length and controlled diameter tolerance prevent lateral movement, reducing wear on mating parts. Combined with the hex socket drive and coarse thread, it ensures quick installation and high clamp load, solving common issues of misalignment and thread failure in high-vibration environments.
