Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and durability challenges in demanding assemblies. The 18-8 stainless steel base material provides excellent resistance to rust and corrosion, while the advanced TiCN coating drastically reduces wear, making it ideal for high-cycle applications in machinery, automation, and precision instruments. The precise shoulder acts as a pivot, bearing surface, or locator, ensuring components remain perfectly aligned without the need for additional bushings or spacers. Its Class 6g metric thread and coarse pitch offer quick assembly and reliable holding power, reducing installation time and maintenance needs in production lines and heavy-duty equipment.

Specification Summary & Compliance
