Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in precision industrial applications. The 316 stainless steel material provides superior resistance to corrosion and oxidation, making it suitable for equipment in chemical processing, marine, and food-grade environments. The 100mm shoulder length acts as a precise pivot or spacer, maintaining component alignment in rotating assemblies, machinery linkages, and automation systems. The Class 5g6g thread fit and coarse M5x0.8 thread ensure reliable engagement and vibration resistance, while the socket head with hex drive allows for compact installation in confined spaces. These features collectively reduce maintenance downtime and enhance the operational lifespan of high-precision mechanical systems.

Specification Summary & Compliance

This metric shoulder screw adheres to precise dimensional standards, including a Class 5g6g thread fit per ISO metric specifications, with shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. Manufacturing and material compliance includes conformity with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring the absence of restricted hazardous substances. The mechanical properties, including tensile and shear strengths, are consistent with industrial fastener requirements for demanding applications.
