Professional Applications & Engineering Value
This M6 shoulder screw is engineered to address critical alignment and corrosion challenges in precision industrial applications. The 316 stainless steel material, combined with a black oxide finish, provides exceptional resistance to chemicals and moisture, reducing maintenance in environments like marine or chemical processing. The 30mm shoulder length and precise diameter tolerance ensure stable positioning of moving parts, such as in pivots or bearing mounts, preventing misalignment and extending component life. With a knurled head and hex drive, it offers secure handling during assembly, while the coarse metric threads facilitate quick installation in high-vibration settings. Ideal for heavy-duty machinery and automotive systems, this screw enhances reliability and reduces downtime.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 standards, with Class 5g6g thread fit for precise tolerance and a shoulder diameter tolerance of -0.072 to -0.01 mm. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and industrial suitability.
