• Precise and secure fit ensured by Class 5g6g thread fit and controlled shoulder diameter tolerance for consistent assembly.
• Easy installation and removal with a standard hex socket head and 3 mm drive, allowing for efficient tool engagement.
• Versatile shoulder design featuring a 14 mm shoulder length to act as a pivot, spacer, or axle in mechanical assemblies.
• Compliance with environmental standards, being RoHS 3 and REACH compliant for safe and sustainable use in regulated industries.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address common industrial challenges such as component misalignment and rotational wear. The 316 stainless steel material offers exceptional resistance to chemicals and saltwater, making it suitable for marine, chemical processing, and food-grade applications. The black oxide finish not only enhances corrosion protection but also reduces galling during installation. With its 14mm shoulder length and Class 5g6g thread, it provides precise location and secure fastening in assemblies like machinery linkages, bearing mounts, and precision instruments, ensuring minimal backlash and extended equipment lifespan. The socket head design with a hex drive allows for compact installation in confined spaces, streamlining maintenance and reducing downtime.

Specification Summary & Compliance

This shoulder screw adheres to metric system specifications with an M5x0.8 coarse thread and Class 5g6g thread fit for standard tolerance. Key dimensional accuracies include a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring compliance for industrial and export requirements. The mechanical properties, including a Rockwell B79 hardness, support reliable performance in high-stress environments.
