Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical stress in precision equipment. The 316 stainless steel material offers excellent resistance to corrosive agents, extending service life in applications like medical devices, automotive assemblies, and electronic enclosures. The black oxide finish not only enhances corrosion protection but also reduces friction during installation. With a knurled socket head and 2mm hex drive, it ensures secure gripping and easy handling in tight spaces, while the Class 5g6g thread fit provides consistent, reliable fastening that withstands vibrations and dynamic loads. Ideal for precision engineering and high-tensile applications, this screw minimizes downtime and maintenance costs.

Specification Summary & Compliance

The screw features a metric thread with M2 x 0.4mm coarse pitch and Class 5g6g thread fit for precise tolerance. Shoulder dimensions include a diameter of 3 mm (tolerance: -0.072 to -0.01 mm) and length of 3 mm (tolerance: 0 to 0.25 mm), ensuring accurate fit in assemblies. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and industrial safety standards.
