Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in industrial assemblies. The 316 stainless steel material offers exceptional resistance to corrosion from chemicals, moisture, and salt, making it suitable for marine, chemical processing, and food-grade equipment. The 45mm shoulder length provides a precise bearing surface for rotating parts like gears and pulleys, minimizing misalignment and reducing friction-induced wear. Combined with the hex socket drive, it allows for high-torque installation in confined spaces, ensuring a secure fit without stripping. The coarse thread pitch and Class 5g6g thread fit enhance vibration resistance, preventing loosening in dynamic applications such as machinery, automation systems, and precision instruments.

Specification Summary & Compliance

This shoulder screw features a metric M5x0.8 thread with a Class 5g6g tolerance for precise fit. The shoulder diameter is 6 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 45 mm with a tolerance of 0 to 0.25 mm, ensuring dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, confirming its adherence to environmental and safety regulations for industrial use.
