Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address common industrial challenges 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 a concern. The precise shoulder with a diameter of 7 mm and length of 10 mm acts as a pivot or spacer, ensuring accurate positioning and reducing stress on threaded sections. Combined with a low socket head and coarse thread pitch of 0.8 mm, it facilitates quick assembly and disassembly, enhancing efficiency in production lines and maintenance operations. This design is ideal for securing rotating parts, guiding moving components, and providing reliable fastening in industrial shoulder screw applications that demand durability and precision.

Specification Summary & Compliance

The screw features a metric thread size M5 with a coarse pitch of 0.8 mm and Class 6g thread fit for standard tolerance. Shoulder dimensions include a diameter of 7 mm (tolerance: -0.036 to 0 mm) and length of 10 mm (tolerance: 0.07 to 0.15 mm), ensuring precise fit. It conforms to DIN 923 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmental and safety standards in global markets.
