Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical alignment and corrosion challenges in precision assemblies. The 316 Stainless Steel construction, enhanced by a Black Oxide finish, provides exceptional resistance to chemicals and moisture, making it suitable for medical devices, marine equipment, and food processing machinery. The 50mm shoulder length ensures accurate component spacing and reduces wear by acting as a pivot or axle. Combined with a Class 5g6g thread fit and hex drive, it offers reliable fastening in tight spaces, minimizing the risk of loosening under vibration. This design is ideal for applications requiring repeated disassembly and reassembly without compromising integrity.

Specification Summary & Compliance

This metric shoulder screw adheres to precise dimensional tolerances, including a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. The thread fit conforms to Class 5g6g standards, ensuring compatibility with metric assemblies. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and suitability for global industrial use.
