Professional Applications & Engineering Value

This precision shoulder screw delivers exceptional value in applications requiring exact positioning and rotational control, such as machinery assemblies, pivoting mechanisms, and precision instruments. The 18-8 stainless steel material provides excellent corrosion resistance while maintaining Rockwell B55 hardness for durability in demanding conditions. The M6x1mm coarse thread with Class 6g fit ensures reliable fastening in vibration-prone environments, while the precisely machined 8mm shoulder diameter acts as a built-in spacer or pivot point, eliminating the need for additional components. The socket head design allows for compact installation in confined spaces, making these metric shoulder screws ideal for automated assembly systems and high-precision engineering applications where repeatability and dimensional accuracy are critical.
