Professional Applications & Engineering Value

This M27x3mm shoulder screw is engineered to solve critical alignment and wear issues in industrial machinery, such as conveyor systems, robotic arms, and precision assembly jigs. The 30mm shoulder diameter with minimal tolerance provides an exact locating surface, reducing component misalignment and extending equipment life. Made from 316 Stainless Steel with a Black Oxide finish, it resists corrosion from chemicals, moisture, and high temperatures, ensuring reliability in demanding environments like food processing or offshore operations. The 70mm shoulder length offers ample support for rotating parts, while the Class 5g6g metric thread and coarse 3mm pitch facilitate quick assembly and high vibration resistance, minimizing maintenance downtime and improving operational efficiency.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 standards, with a Class 5g6g thread fit for precise metric threading. Key dimensions include a shoulder diameter of 30 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 70 mm (tolerance: 0 to 0.25 mm), ensuring high dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), meeting environmental and safety regulations for industrial use.
