Professional Applications & Engineering Value
This M2 shoulder screw is engineered to solve critical alignment and corrosion challenges in precision assemblies. The 316 stainless steel material provides exceptional resistance to chemicals and saltwater, making it perfect for marine, chemical processing, and food-grade equipment. The long, 40mm precision shoulder acts as a reliable pivot or spacer, eliminating misalignment in rotating parts, linkages, and guide mechanisms. The black oxide finish not only adds a layer of corrosion protection but also reduces galling. Combined with the knurled socket head and hex drive, it ensures secure, tool-friendly installation in tight spaces, reducing assembly time and improving the reliability of high-stress mechanical systems.
Specification Summary & Compliance
This screw features a Class 5g6g thread fit per metric standards, ensuring precise and consistent thread engagement. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, guaranteeing high dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for use in environmentally conscious and regulated industrial applications.
