Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and mounting challenges in precision assemblies. The 316 Stainless Steel material offers exceptional resistance to corrosion from chemicals, moisture, and salt spray, making it suitable for food processing, marine, and pharmaceutical equipment. The integrated 20mm shoulder acts as a precise pivot or spacer, eliminating the need for additional components and reducing assembly time. Combined with the Class 5g6g thread fit and hex socket drive, it ensures secure fastening in high-vibration environments like robotics and automation systems, providing long-term reliability and reducing maintenance downtime.
Specification Summary & Compliance
This metric shoulder screw features an M5x0.8 coarse thread with a Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm for precise engineering fits. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications.
