Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical challenges in precision assembly, such as misalignment and component wear. The 316 stainless steel material offers exceptional resistance to chemicals and moisture, preventing failure in demanding conditions like marine or chemical processing equipment. The 15mm shoulder length acts as a precise pivot or spacer, ensuring accurate positioning of parts in machinery, electronic enclosures, and optical devices. Combined with the Class 5g6g thread fit and coarse 0.4mm pitch, it provides secure fastening that resists loosening from vibrations, common in automotive or automation systems. The socket head with 2mm hex drive allows for compact installation in confined spaces, enhancing design flexibility and maintenance efficiency for engineers and OEMs.

Specification Summary & Compliance

This shoulder screw conforms to Metric system standards with an M2 thread size and 0.4mm coarse pitch. The thread is manufactured to Class 5g6g tolerance for consistent fit. Shoulder dimensions include a diameter of 3 mm (tolerance: -0.072 to -0.01 mm) and length of 15 mm (tolerance: 0 to 0.25 mm). It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
