• High mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable performance under load.
• Precise component alignment enabled by the smooth, 18mm long shoulder with controlled diameter tolerance.
• Secure and flush installation with a smooth socket head and 3 mm hex drive, minimizing protrusion.
• Durable and wear-resistant surface due to the black oxide finish and Rockwell B79 hardness.
• Wide industrial compatibility with a coarse M5x0.8 metric thread and Class 5g6g fit for easy assembly.
• Compliance with global regulations, including RoHS 3 and REACH, ensuring environmental and safety standards are met.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and fastening challenges in demanding industrial applications. The 316 stainless steel material provides exceptional resistance to corrosion from chemicals, saltwater, and atmospheric exposure, making it suitable for machinery, marine equipment, and food processing systems. The precision 18mm shoulder acts as a pivot, shaft, or spacer, ensuring accurate location of assembled parts and reducing wear on components. The black oxide finish not only enhances corrosion protection but also reduces galling during installation. With its hex socket drive and right-hand coarse thread, it allows for high torque application and quick assembly, streamlining production and maintenance processes where reliability is paramount.

Specification Summary & Compliance

This shoulder screw features an M5x0.8 metric thread with a Class 5g6g tolerance for precise fit.
