Professional Applications & Engineering Value
These M5 shoulder screws deliver critical precision in applications requiring exact component alignment and secure fastening. The 18-8 stainless steel material provides excellent corrosion resistance, making them ideal for machinery, automotive, and electronic assemblies exposed to moisture or chemicals. The coarse thread pitch (0.8mm) ensures quick installation and high vibration resistance, while the hex socket drive allows for high-torque application in confined spaces. The precisely machined shoulder diameter (5mm) acts as a pivot or axle, eliminating the need for additional bushings and reducing assembly complexity. With Rockwell B55 hardness, these screws maintain dimensional stability under stress, preventing deformation in dynamic industrial environments.
Specification Summary & Compliance
Manufactured to metric system standards with M5 x 0.8mm coarse threads and Class 5g6g thread fit for precision tolerance. Shoulder diameter tolerance maintained at -0.072 to -0.01 mm with shoulder length tolerance of ±0.05 mm. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets.
