    L-Keys

    Image of Product. Front orientation. L-Keys. L-Keys.
    The highest quality L-keys you can buy for tightening and loosening screws. Our L-keys are precision manufactured to tight tolerances for an exact fit.
    Alloy Steel—These L-keys handle high torque without bending or breaking, so they’ll last a lifetime.
    Short—A short long leg fits into tight spaces where you have less room to swing, making these ideal for confined areas.
    Long—The most common option, these L-keys have a balanced length for everyday reach and torque.

    L-Key

    The assorted keys in these sets have a small handle that prevents you from generating too much torque when turning a fastener. They are often used to install carbide inserts in cutting tools.
    Black Phosphate-Coated Steel—These keys resist rust in most wet and outdoor applications, however, they won't hold up to salt water and chemicals.
