Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and pivot point challenges in industrial machinery. The 316 stainless steel material offers exceptional resistance to chemicals and moisture, preventing failure in corrosive settings like marine or chemical processing equipment. The 10mm shoulder diameter and 25mm shoulder length provide a precise unthreaded bearing surface, reducing wear on mating parts and maintaining accurate positioning in assemblies such as rotating shafts, linkages, and guides. Combined with the coarse M5x0.8 thread and socket head design, it ensures quick, secure fastening in high-vibration environments, delivering long-term durability and reduced maintenance for engineers and OEMs.

Specification Summary & Compliance

This metric shoulder screw features precise dimensional controls, including a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. The thread fit conforms to Class 5g6g per metric standards, ensuring reliable performance. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for environmentally conscious industrial applications.
