• Easy installation and grip thanks to the knurled socket head and 4mm hex drive, reducing slippage during torque application.
• Accurate component alignment with a precisely machined 8mm shoulder diameter and controlled length tolerances.
• Compliance with global regulations including RoHS 3 and REACH, making it suitable for international supply chains and sensitive applications.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and assembly jigs where alignment and corrosion resistance are paramount. The 316 stainless steel material provides excellent resistance to chlorides and acidic conditions, reducing maintenance downtime in marine, chemical processing, and food industry equipment. The black oxide finish not only enhances corrosion protection but also minimizes friction during installation. With its knurled socket head and 4mm hex drive, it ensures secure tool engagement, preventing stripping in high-torque scenarios. The Class 5g6g thread fit and controlled shoulder dimensions guarantee repeatable positioning in metric assemblies, making it a reliable choice for pivots, spacers, and rotating components that demand long-term reliability and minimal backlash.

Specification Summary & Compliance

This shoulder screw adheres to metric standards with an M5x0.8mm coarse thread and Class 5g6g thread fit for precise tolerance control. The shoulder diameter is manufactured to 8 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 4 mm with a 0 to 0.25 mm tolerance, ensuring consistent fit in precision applications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industrial markets.
