• Reliable thread engagement with a Class 5g6g thread fit and M6x1 coarse thread, enabling quick assembly and vibration resistance.
• Long-lasting durability from the 60mm shoulder length, offering extended bearing surface and reducing wear on connected components.
• Global compliance and safety meeting ISO 7379 standards and being RoHS 3 and REACH compliant for use in regulated industries.

Professional Applications & Engineering Value

This M6x1 shoulder screw is engineered to address critical alignment and pivot point challenges in industrial machinery. The 60mm shoulder length and 8mm shoulder diameter provide a precise, unthreaded bearing surface that eliminates the need for separate spacers or bushings, reducing part count and assembly time. Manufactured from 18-8 Stainless Steel, it offers excellent corrosion resistance, which is vital for equipment in moist or chemically aggressive environments. The hex socket drive and knurled head texture ensure secure installation with standard tools, preventing slippage and enhancing worker safety. Ideal for applications in robotics, conveyor systems, and automotive assemblies, this metric shoulder screw delivers reliable performance, minimizes maintenance, and supports efficient production lines by withstanding high shear and tensile loads.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per ISO metric standards, ensuring precise thread engagement and interchangeability. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, providing high dimensional accuracy for consistent performance. It is manufactured in compliance with ISO 7379 specifications and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, confirming its suitability for use in environmentally sensitive and regulated industrial applications.
