Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve common alignment and assembly challenges in industrial settings. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for machinery, electronic enclosures, and fixtures exposed to moisture or chemicals. The knurled thumb head allows for quick manual adjustments without tools, while the integrated hex drive offers additional torque application when needed. The precise shoulder (6mm diameter, 8mm length) acts as a pivot or spacer, ensuring perfect alignment of components and reducing stress on the M5 coarse thread. This design minimizes assembly errors, speeds up maintenance, and enhances the longevity of the final product, providing significant engineering value in prototyping, manufacturing, and equipment repair.

Specification Summary & Compliance

This M5 shoulder screw features a Class 6g thread fit per metric standards, with a coarse thread pitch of 0.8mm for efficient assembly. The shoulder maintains tight tolerances (diameter: -0.025 to 0 mm; length: 0 to 0.05 mm) to ensure precise fitment. Manufactured from 18-8 stainless steel, it meets key industry regulations, including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances for safe use in various industrial applications.
