Professional Applications & Engineering Value

This M6 set screw is engineered to address critical fastening challenges in industrial settings, where vibration resistance and long-term reliability are paramount. Made from alloy steel and heat-treated to Rockwell C39 hardness, it withstands high stress and repetitive loads without loosening, making it ideal for securing gears, pulleys, and shafts in machinery. The ball tip minimizes marring on contacted surfaces, while the hex drive and coarse thread pitch enable rapid installation in tight spaces. Its headless design ensures a flush fit, preventing interference in assemblies. Commonly used in automotive, manufacturing, and heavy equipment, this screw provides a robust solution for precision fastening that maintains integrity under extreme conditions.

Specification Summary & Compliance

This set screw adheres to metric standards with M6 thread size, 1 mm coarse pitch, and Class 6g thread fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) compliance under exemption 6(a) for lead as an alloying element in steel, ensuring environmental safety. The manufacturing process focuses on consistency in length (20.8 mm), tip diameter (4 mm), and material properties, supporting reliable performance in industrial applications requiring high-strength fastening.
