• Precise alignment and reduced wear thanks to the accurately machined shoulder with 8mm diameter and 16mm length, maintaining component positioning.
• High strength and durability with Rockwell B95 hardness and 80,000 psi tensile strength, suitable for demanding mechanical applications.
• Easy installation in confined spaces using the low-profile socket head and 4mm hex drive, allowing efficient assembly with standard tools.
• Reliable thread engagement with Class 6g thread fit and M6x1mm coarse pitch, providing secure fastening and vibration resistance.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.
• Consistent performance due to tight tolerances on shoulder diameter and length, minimizing play and enhancing operational stability.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address common industrial challenges such as misalignment, component wear, and corrosion-induced failure. The 18-8 stainless steel material, combined with a passivated finish, offers excellent resistance to rust and chemicals, making it ideal for machinery, automotive assemblies, and electronic enclosures exposed to moisture or aggressive substances. The low-profile socket head design allows for compact installations where space is limited, while the precise shoulder fit ensures accurate alignment of moving parts, reducing friction and extending service life. With a Class 6g thread fit and coarse 1mm pitch, it facilitates quick assembly and disassembly, saving time in maintenance and production lines. These features make it a reliable choice for industrial applications requiring durability, precision, and compliance with stringent regulations.
