Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications such as machinery assemblies, pivoting mechanisms, and precision equipment. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, extending service life in humid or chemically aggressive settings. The 35mm shoulder length provides a stable bearing surface that prevents axial movement and reduces stress on threaded sections, while the knurled hex socket head ensures a firm grip for efficient installation and removal with standard 3mm hex drive tools. Its Class 5g6g thread fit and coarse pitch facilitate rapid assembly without compromising strength, making it a reliable choice for high-vibration environments and repetitive disassembly needs.

Specification Summary & Compliance

This shoulder screw features a shoulder diameter of 6 mm with a tolerance of -0.04 to -0.01 mm and a shoulder length of 35 mm with a tolerance of 0 to 0.25 mm, ensuring precise dimensional accuracy. The metric thread adheres to Class 5g6g fit standards for consistent performance. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and safe industrial use.
