• Precise component alignment and location thanks to the smooth, 3 mm diameter shoulder with a precise fit and tight tolerances.
• Secure and efficient installation using a standard 1.5 mm hex drive, providing a positive grip and reducing the risk of tool slippage.
• Wide compatibility and interchangeability with a Class 6g metric coarse thread (M2 x 0.4 mm), conforming to standard engineering specifications.
• Compliance with global environmental regulations including RoHS 3 and REACH, ensuring safe and responsible use in various markets.

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical alignment and spacing challenges in precision assemblies. The 316 stainless steel material offers exceptional resistance to chemicals and saltwater corrosion, making it a robust choice for industrial applications in marine, chemical processing, and food machinery. The precise shoulder with its controlled diameter and length acts as a pivot, bearing surface, or locator, eliminating the need for additional spacers or bushings and simplifying assembly. The socket head with a 1.5 mm hex drive allows for high-torque installation in confined spaces, while the Class 6g thread ensures a reliable fit with mating components. The passivated finish further enhances surface durability, preventing galling and seizing during repeated use.

Specification Summary & Compliance

This precision shoulder screw features an M2 x 0.4 mm coarse metric thread with a Class 6g tolerance fit. The shoulder maintains a diameter of 3 mm with a tolerance of -0.025 to 0 mm and a length of 8 mm with a tolerance of 0 to 0.05 mm, ensuring a precise fit. The product is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent international standards for hazardous substance restrictions.
