• High mechanical strength and durability with a tensile strength of 70,000 psi and Rockwell B79 hardness for demanding applications.
• Reliable and coarse thread engagement with M6x1mm Class 5g6g threads, facilitating faster assembly and reduced cross-threading risk.
• Compliance with international standards including ISO 7379, ensuring interchangeability and quality in global manufacturing.
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting strict regulatory requirements.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 316 Stainless Steel material provides exceptional resistance to corrosion and oxidation, making it suitable for marine, chemical processing, and food-grade equipment where moisture and aggressive substances are present. The knurled socket head and 4mm hex drive offer secure tool engagement, minimizing wear and ensuring consistent fastening in automated or manual production lines. The precisely machined 5mm shoulder acts as a pivot or spacer, maintaining accurate positioning of moving parts in machinery, robotics, and conveyor systems. By integrating a coarse metric thread (M6x1mm) with Class 5g6g tolerance, it enables quick installation and reliable performance under vibration, reducing maintenance downtime and enhancing operational efficiency.
