    Hex Nuts
    3D CAD models available

    Image of Product. Front orientation. Hex Nuts. Hex Nuts.
    The most commonly used hex nuts, these are suitable for fastening most machinery and equipment.
    Extreme-Strength Steel
    Rated Grade 9 or Class 12, these nuts are about 20% stronger than high-strength steel nuts. They are strong enough to secure components in heavy machinery, such as bulldozers and excavators. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.
    Cadmium Yellow-Chromate-Plated Steel— The plating creates a barrier against rust, so these nuts are suitable for most wet and outdoor environments. They also thread on smoothly without sticking.

    Top-Lock Distorted-Thread Locknuts
    3D CAD models available

    Image of Product. Front orientation. Locknuts. Top-Lock Distorted-Thread Locknuts.
    Irregularly shaped threads at the top of these locknuts grip the screw for a stronger hold than nylon-insert locknuts. Although the threads prevent the nut from backing out due to vibration, they also increase the effort to install and remove. To get these nuts off, you may need special tools, such as an impact wrench or propane torch. Nuts are not reusable.
    Extreme-Strength Steel
    About 20% stronger than high-strength steel locknuts, these Grade 9 nuts are the strongest we offer. Make sure to use them with Grade 9 screws to avoid stripped threads during installation.
    Cadmium-Plated Steel—These locknuts have good lubricity to thread on smoothly and ease installation. The plating also creates a barrier against rust that's comparable to zinc-yellow-chromate plating.
