Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and strength challenges in industrial applications. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for machinery, automotive assemblies, and electronic enclosures exposed to moisture or chemicals. The precision shoulder (10mm length with controlled tolerances) acts as a pivot or spacer, ensuring accurate positioning of moving parts like gears, bearings, and linkages, which reduces wear and misalignment. Combined with the coarse metric thread and socket head design, it allows for high-torque fastening in confined spaces, streamlining maintenance and improving overall assembly reliability in high-vibration environments.
Specification Summary & Compliance
The screw features a Class 5g6g thread fit per metric standards, with shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm for precise engineering use. It is manufactured in accordance with ISO 7379 and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability in production and application.
