• High load-bearing capacity with a tensile strength of 70,000 psi and a minimum shear strength of 35,000 psi for demanding applications.
• Reliable and consistent thread engagement due to the Class 5g6g thread fit, reducing the risk of assembly issues.
• Secure, non-slip fastening enabled by the knurled head and 5mm hex socket drive, allowing for high-torque installation.
• Compliance with stringent environmental regulations, including RoHS 3 and REACH, ensuring safety and global market acceptance.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical challenges in industrial assembly, such as misalignment and component wear. The 316 stainless steel material offers excellent resistance to chemicals and moisture, making it suitable for marine, chemical processing, and food machinery applications. The black oxide finish not only enhances corrosion protection but also reduces friction during operation. The precise 16mm shoulder length and 10mm shoulder diameter provide a stable bearing surface for rotating parts, minimizing play and extending equipment life. With its coarse thread pitch and Class 5g6g thread fit, it ensures quick assembly and reliable performance in high-vibration environments, delivering consistent engineering value for precision shoulder screws in automated systems and heavy-duty machinery.
