Professional Applications & Engineering Value
This alloy steel set screw is engineered to address common industrial challenges such as component slippage and loosening under dynamic loads. The cup point tip creates a permanent indentation in the mating surface, providing excellent resistance to vibration and rotational forces in machinery, automotive assemblies, and precision equipment. With its M8 coarse thread and Class 5g6g thread fit, it ensures rapid assembly and reliable torque transmission, reducing downtime in production lines. The Rockwell C45 hardness enhances its lifespan in high-wear scenarios, while the headless design and 4mm hex drive facilitate use in tight spaces, offering a dependable solution for securing collars, gears, and pulleys without protruding elements.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards with M8 x 1.25mm coarse thread and Class 5g6g thread fit per ISO metric specifications, ensuring accurate and consistent performance. It meets DIN 916 and ISO 4029 manufacturing standards for quality and reliability. Additionally, the product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in various industrial applications without hazardous substances.
