• Secure and efficient installation using the 2mm hex socket drive, allowing for high torque application in confined spaces.
• Accurate and consistent threading with Class 5g6g metric thread fit, ensuring compatibility and reducing the risk of cross-threading.
• Compliance with environmental standards including RoHS 3 and REACH, making it suitable for regulated industries.

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical challenges in precision assemblies, such as in electronics, machinery, and automotive components. The 316 stainless steel material offers excellent resistance to chemicals and moisture, preventing failure in corrosive conditions. The black oxide finish not only enhances corrosion protection but also reduces galling during installation. With a 16mm shoulder length and precise Class 5g6g thread fit, it ensures accurate pivoting and alignment in rotating parts, minimizing wear and maintenance. The hex socket drive allows for secure fastening in tight spaces, making it a reliable choice for applications demanding high tensile strength and long-term performance in industrial settings.

Specification Summary & Compliance

This shoulder screw features a metric M2 x 0.4mm coarse thread with Class 5g6g thread fit for precise tolerance. The shoulder diameter is 3 mm with a tolerance of -0.072 to -0.01 mm, and shoulder length is 16 mm with a tolerance of 0 to 0.25 mm, ensuring consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industrial applications.
