This guarantees high tensile strength and durability, essential for strong and secure fastenings in various applications. ### Fine UNF thread for precise assembly Equipped with a Unified National Fine (UNF) thread with 28 threads per inch, this bolt offers a finer thread than the standard UNC variant. This results in better grip and more precise assembly, which is especially important in applications where precision is required. ### Electroplated finish for corrosion resistance The electroplated finish protects the bolt against corrosion and rust, significantly extending its lifespan. This makes the bolt suitable for use in humid environments or applications where exposure to the elements is inevitable. ### Hex head for easy installation The hex head allows the bolt to be easily tightened with standard tools such as a wrench or socket. The wrench size is 7/16 inch, providing a firm grip during tightening. ### Versatile use in various sectors Thanks to the combination of strength, precision, and corrosion resistance, this hex bolt is ideal for use in the automotive sector, mechanical engineering, and other industrial applications where reliable fastening is essential. -
