• Rockwell B79 hardness provides excellent wear resistance, maintaining thread integrity and shoulder dimensions over repeated use.

Professional Applications & Engineering Value

This M6x1mm metric shoulder screw is engineered to solve critical alignment and durability challenges in industrial assemblies. The 316 stainless steel material, combined with a black oxide finish, offers exceptional resistance to corrosion from chemicals, moisture, and salt spray, making it ideal for marine, chemical processing, and outdoor equipment. The precisely machined shoulder with a diameter of 8 mm and length of 125 mm acts as a reliable locating pin or bearing surface, reducing wear on mating components and simplifying assembly in machinery, automation systems, and precision instruments. The coarse right-hand thread and hex socket drive enable quick, secure fastening, while the knurled head enhances grip during manual adjustments. By meeting ISO 7379 standards, this screw ensures dimensional consistency and performance reliability, minimizing downtime in high-stress applications like robotics, conveyor systems, and automotive jigs.
