    About Hex Nuts
    industrial info icon

    Choose a hex nut with the right profile, material, and strength for your application.

    Structural Heavy-Profile Hex Nuts

    These nuts are designed to secure ASTM A325 screws in structural joints, such as mating I-beams, columns, and joists. About 10% wider and taller than standard-profile hex nuts, they handle heavier loads by distributing them over a larger area.
    High-Strength Steel

    Rated Grade 8, Grade C, or Class 10, these nuts are about 25% stronger than medium-strength steel nuts. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.
    Black-Oxide Steel—Typically chosen for their appearance, these nuts have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
