• Enhanced mechanical strength with 70,000 psi tensile strength and Rockwell B79 hardness for reliable load-bearing applications
• Secure torque transmission through the 4mm hex socket drive, preventing stripping during installation
• Accurate thread engagement with Class 6g thread fit and coarse M6x1mm pitch for quick, stable fastening
• Consistent dimensional control with 10mm shoulder length tolerance (0 to 0.05 mm) for repeatable precision in manufacturing
• Compliance with global standards including RoHS 3 and REACH, ensuring environmental and safety regulations are met

Professional Applications & Engineering Value

This M6 shoulder screw delivers critical engineering value in precision alignment applications where component positioning is paramount. The 316 stainless steel material combined with a passivated finish provides exceptional resistance to corrosive agents, making it suitable for chemical processing, marine, and food industry equipment. The precisely machined 8mm shoulder diameter acts as a reliable locating dowel, eliminating misalignment in assemblies like rotating shafts, bearings, and gears. With its Class 6g thread and coarse M6x1mm pitch, it ensures rapid installation and vibration resistance in automated machinery. The socket head hex drive allows for high-torque application in confined spaces, reducing assembly time while maintaining structural integrity under 70,000 psi tensile loads.
