Professional Applications & Engineering Value
This M5 shoulder screw is engineered to solve critical alignment and wear challenges in industrial applications. The 18-8 stainless steel core provides excellent corrosion resistance, while the TiCN coating significantly enhances surface durability, reducing galling and wear in high-movement assemblies like pivots, linkages, and rotating machinery. The precise shoulder with its controlled diameter and length acts as a reliable datum for locating components, eliminating misalignment and simplifying assembly. Combined with the Class 6g metric thread, it ensures a secure fit that withstands operational vibrations, making it a vital precision fastener for automation equipment, precision instruments, and other demanding engineering systems.
Specification Summary & Compliance
This screw features an M5 x 0.8mm coarse thread with a Class 6g tolerance for reliable fit. The shoulder is manufactured to a precise diameter tolerance of -0.025 to 0 mm and a length tolerance of 0 to 0.05 mm. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances for safe use in various global markets.
