Professional Applications & Engineering Value
This M6 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in machinery. The 18-8 Stainless Steel material offers excellent corrosion resistance, ideal for applications in humid or chemically exposed environments like automotive assemblies, conveyor systems, and precision instruments. The 45mm shoulder length provides a stable bearing surface, allowing for precise positioning of moving parts like gears and pulleys without additional bushings. Combined with the hex socket drive and knurled head texture, it ensures quick, secure installation with standard tools, reducing assembly time and improving maintenance efficiency in high-volume production settings.
Specification Summary & Compliance
The screw features a Class 5g6g thread fit per metric standards, with a shoulder diameter tolerance of -0.04 to -0.01 mm and length tolerance of 0 to 0.25 mm for high dimensional accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
