Professional Applications & Engineering Value
This M6 shoulder screw is engineered to address critical assembly challenges in industrial settings. Manufactured from 316 Stainless Steel, it provides exceptional resistance to corrosion and chemicals, making it suitable for marine, chemical processing, and food-grade equipment. The precision shoulder diameter acts as a pivot, bearing, or spacer, ensuring accurate alignment of components like gears, pulleys, and linkages, which reduces wear and prevents misalignment. The coarse metric thread (M6x1mm) and Class 5g6g thread fit allow for quick assembly and high resistance to loosening under vibration. Combined with the hex socket drive and knurled head, it offers secure, tool-friendly installation in confined spaces, enhancing productivity and reliability in automated machinery, precision instruments, and heavy-duty assemblies.
Specification Summary & Compliance
This shoulder screw features an M6x1mm coarse thread with a Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. 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 tolerance of 0 to 0.25 mm, providing precise fits for engineering applications. It is manufactured in compliance with ISO 7379 and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial use without hazardous substances.
