Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical challenges in precision assemblies, such as providing a precise pivot point or shaft in machinery, electronics, and automotive components. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, while the black oxide finish enhances surface durability and reduces galling. The 40mm shoulder length ensures accurate spacing and alignment, minimizing misalignment and component wear. With a Rockwell B83 hardness and high tensile strength, it withstands repetitive loads and vibrations, making it ideal for industrial fasteners in high-stress environments. The hex drive socket head and knurled texture facilitate easy installation in confined spaces, improving assembly efficiency and reliability.

Specification Summary & Compliance

This precision shoulder screw features a Class 5g6g thread fit for consistent metric threading, with a shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm to ensure dimensional accuracy. It adheres to standard metric thread specifications and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally conscious and safe industrial applications.
