Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical challenges in precision assemblies, such as misalignment and component wear. The 18-8 Stainless Steel material provides excellent corrosion resistance, making it suitable for applications in machinery, automotive, and electronics where exposure to moisture or chemicals is common. The 12mm shoulder diameter acts as a precise pivot or spacer, ensuring accurate positioning of parts like gears and bearings, which reduces downtime and maintenance costs. Combined with the coarse thread and Class 5g6g thread fit, it allows for rapid, secure fastening in high-vibration environments, enhancing overall assembly reliability. The knurled head and hex drive further contribute to easy installation and removal, streamlining production workflows.
Specification Summary & Compliance
This shoulder screw features a metric M8x1.25 thread with Class 5g6g thread fit for precise tolerance, and a shoulder diameter of 12 mm with tolerance from -0.072 to -0.01 mm. It complies with ISO 7379 manufacturing standards and is verified to be RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental safety and adherence to international regulations.
