    Keep a selection of top-quality L-keys on hand, so you always have the size you need. Our L-keys are precision manufactured to tight tolerances for an exact fit and withstand high torque without bending or breaking. Made of hardened steel or stainless steel, they'll last a lifetime in your tool kit.
    Gold-Plated Steel—The 14-Karat gold finish resists corrosion better than black oxide to withstand rust in most wet and outdoor applications. However, gold is not as hard as other finishes, so it may wear off over time.

    Turn screws at an angle when you can't access them head on. These L-key sets have a ball tip on the long leg that engages the drive with less contact than a straight tip. Ball tips are handy for corners and tightly-packed areas, such as control panels and junction boxes. However, they don't grip as tightly as straight tips, and may strip the drive of the fastener if you crank them too hard. These L-keys are precision manufactured to tight tolerances. Made from high-quality hardened steel, they'll last a lifetime in your tool kit.
