    Brass Hex Panel Nuts

    Image of Product. Front orientation. Panel Nuts. Brass Hex Panel Nuts.
    These panel nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. They can be fastened with a wrench for more torque while tightening than knurled panel nuts. Also known as dress nuts, they're extremely thin for use in tight spaces such as electrical panels.

    Left-Hand-Thread Thin-Profile Hex Nuts

    These nuts tighten when turned to the left. Use them with left-hand rods and screws to prevent counterclockwise-moving parts from loosening. About half the height of standard-profile nuts, these fit in spaces with low clearance. You can also use them as jam nuts by threading them against another hex nut to hold it in place.
    Low-Strength Steel
    Image of Product. Front orientation. Contains Annotated, MultipleImages. Hex Nuts. Left-Hand-Thread Thin-Profile Hex Nuts.
    Rated Grade 2, Class 6, or lower, these nuts are about half as strong as medium-strength nuts. They are suitable for light duty fastening applications, such as securing access panels. Use them with screws that have a similar strength rating to avoid stripping threads during installation.
    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.

    Round Coupling Nuts

    Less bulky than hex coupling nuts, these have a smooth, round body that fits in tight spots. Their finished appearance makes them a common choice for decorative applications. Tighten by hand, or use soft-jaw pliers to avoid marring the outside surface. Also known as extension nuts, they are commonly used to connect lengths of threaded rod and join threaded parts.
