Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and wear challenges in precision assemblies. The 25mm shoulder length acts as a precise pivot or spacer, reducing friction and misalignment in rotating parts like gears, pulleys, and linkages. Made from 18-8 stainless steel with a black oxide finish, it offers superior corrosion resistance, extending service life in moist or chemically exposed settings. The coarse M5x0.8 thread and Class 5g6g fit ensure quick, secure fastening with minimal risk of cross-threading, while the hex socket drive supports high-torque applications in confined spaces. Ideal for robotics, automotive, and machinery, this fastener enhances assembly reliability and reduces maintenance downtime.
Specification Summary & Compliance
This shoulder screw features a M5x0.8 metric thread with Class 5g6g tolerance for precise fit, a shoulder diameter of 6 mm (tolerance: -0.072 to -0.01 mm), and shoulder length of 25 mm (tolerance: 0 to 0.25 mm). It meets ISO 7379 standards for dimensional consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no hazardous substances are used.
