Grade 2 Finished Hex Nuts Zinc Plated

CURRENT SELECTIONS

Grade 2 finished hex nuts are six-sided threaded fasteners made from low carbon steel and designed for general use. When zinc plated, these nuts receive a protective layer that enhances their resistance to corrosion, making them suitable for various applications. Key specifications and characteristics may vary based on product size.

  • Dimensions:

    • Thickness: Approximately (0.875D), where (D) is the nominal size of the nut.

    • Width Across Flats: (1.5D)

  • Material Composition:

    • Made from low carbon steel with the following chemical composition:

      • Carbon: Maximum 0.47%

      • Phosphorus: Maximum 0.12%

      • Sulfur: Maximum 0.23%

  • Mechanical Properties:

    • Tensile Strength: Specified minimum tensile strength of 74,000 psi.

    • Hardness: Rockwell hardness ranges from B68 to C32.

  • Proof Load:

    • Coarse thread: 68,000 psi

    • Fine thread: 60,000 psi

  • Plating:

    • Zinc plating provides protection against moisture, salt, and other corrosive conditions, enhancing durability and lifespan in outdoor or harsh environments.

  • Applications/Advantages:

    • These nuts are versatile and widely used in construction and manufacturing. They are designed to be used with low carbon bolts and screws, providing reliable fastening solutions for various structural applications
