Professional Applications & Engineering Value

This M12 shoulder screw with metric coarse thread and precision shoulder dimensions solves critical alignment challenges in industrial machinery and automation systems. The 13 mm shoulder diameter with exceptionally tight tolerance provides exact locating functions in rotating assemblies, while the 54.5 mm shoulder length maintains proper spacing between components. Manufactured from steel with Rockwell C20 hardness, this external hex head shoulder screw withstands repetitive motion and high stress in applications ranging from conveyor systems to precision manufacturing equipment. The Class 6g thread fit ensures consistent clamping force while the coarse thread spacing prevents cross-threading during high-volume assembly operations.
