Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion-induced failure, and assembly inefficiency. The 316 stainless steel material provides exceptional resistance to corrosive agents, making it suitable for marine, chemical processing, and outdoor equipment. The black oxide finish not only enhances corrosion protection but also reduces galling during installation. With a knurled socket head and hex drive, it allows for secure tool engagement in confined spaces, minimizing slippage and improving workflow speed. The precise shoulder diameter and length ensure accurate component spacing and rotational stability in precision instruments, automation systems, and electronic enclosures, reducing downtime and maintenance costs.

Specification Summary & Compliance

This metric shoulder screw adheres to Class 5g6g thread fit standards, ensuring tight tolerances for reliable performance. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, providing consistent dimensional accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industries.
