Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and rotational challenges in precision assemblies. The 316 stainless steel material provides exceptional resistance to corrosion and high temperatures, making it suitable for industries like automotive, robotics, and food processing where exposure to moisture and chemicals is common. The black oxide finish reduces friction and prevents seizing, while the knurled head and hex socket drive allow for secure, tool-friendly installation in confined spaces. The precisely machined shoulder with tight diameter and length tolerances ensures accurate component positioning, reducing wear and maintenance in moving parts such as gears, pulleys, and linkages. By integrating ISO 7379 specifications, this fastener delivers consistent performance and longevity in high-stress applications.

Specification Summary & Compliance

This shoulder screw features an M6x1mm coarse metric thread with Class 5g6g tolerance for precise fit. The shoulder diameter is 8 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 6 mm with a 0 to 0.25 mm tolerance. It complies with ISO 7379 manufacturing standards and is verified to be RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to international safety and environmental regulations.
