This guarantees high tensile strength and durability, essential for strong and secure connections in various applications. ### Fine UNF thread for precise assembly The bolt features a Unified National Fine (UNF) thread, which provides a finer pitch and therefore more precise and stronger connections. This is especially beneficial in situations where precision and reliability are required. ### Electroplated finish for extra protection Thanks to the electroplated finish, the bolt is protected against corrosion. This extends its lifespan and ensures the bolt is suitable for use in environments where exposure to moisture or other corrosive elements occurs. ### Standard dimensions for versatile use With a diameter of 5/8 inch and a length of 3.1/2 inch, this bolt complies with the ASME B18.2.1 standard. This makes it compatible with a wide range of applications and easy to combine with other fasteners that meet the same standard. ### Easy installation with standard tools The hexagonal head allows the bolt to be easily installed and removed with standard tools. This saves time and effort during installation and maintenance. ### Suitable for various applications This hex bolt is ideal for use in the automotive sector, machine building, and other industrial applications where strong and reliable fastenings are necessary. The combination of material strength, thread type, and finish makes it highly versatile. - Material: Steel Grade 5 (strength class 8.8) - Thread: UNF (Unified National Fine) - Finish: Electroplated -
