Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical challenges in precision assembly and machinery. The 316 Stainless Steel material provides exceptional resistance to corrosion and chemicals, making it suitable for medical devices, marine equipment, and food processing machinery where hygiene and durability are paramount. The black oxide finish not only enhances corrosion protection but also reduces light reflection, which is beneficial in optical and electronic enclosures. The knurled head and hex socket drive allow for secure tightening in confined spaces, minimizing the risk of stripping. With a coarse thread pitch and Class 5g6g thread fit, it ensures rapid installation and maintains clamp load under dynamic stresses, reducing maintenance needs in automated systems and precision instruments.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M2 thread size and 0.4 mm coarse pitch. The thread fit conforms to Class 5g6g for consistent engagement and assembly precision. Shoulder diameter tolerance is tightly controlled at -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring reliable alignment in jigs and rotating assemblies. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, affirming its suitability for regulated industrial and electronic applications without hazardous substances.
