    Heavy-Profile Hex Nuts for Structural Applications
    3D CAD models available

    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.
    Hot-Dipped Galvanized Steel—Combines the strength of steel with the rust resistance of stainless steel. These nuts are an economical alternative to 18-8 stainless steel in wet and outdoor environments, but they won't hold up to salt water and chemicals. The galvanized finish is thicker than other types of coatings, so the threads may be more likely to stick during installation. Use with other hot-dipped galvanized fasteners.
