Professional Applications & Engineering Value
This precision shoulder screw is engineered to solve critical alignment and durability challenges in industrial machinery. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, extending service life in demanding environments. The 6mm shoulder diameter with precise tolerances acts as a pivot, bearing surface, or spacer, ensuring accurate component positioning in assemblies like rotating shafts, gears, and linkages. The hex socket drive allows for high-torque installation in confined spaces, while the Class 6g M5x0.8 coarse thread ensures rapid assembly and reliable holding power. Ideal for industrial automation, precision equipment, and conveyor systems, this fastener reduces maintenance downtime and improves mechanical reliability.
Specification Summary & Compliance
This M5 shoulder screw features a Class 6g thread fit per metric standards, with a shoulder diameter tolerance of -0.025 to 0 mm and shoulder length tolerance of 0 to 0.05 mm for precision assembly. Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets international environmental and safety standards for industrial components.
