    T-Handle Key Sets

    Image of Product. Front orientation. T-Handle Keys. T-Handle Key Sets.
    Keep a selection of top-quality T-handle keys on hand, so you always have the size you need. They're perfect for cranking screws in large machinery, such as engines and CNC mills. A wide handle gives you maximum leverage, and a long shaft reaches into deep pockets. The shaft is permanently bonded to the handle for a secure hold that won't break under high torque. To prevent slipping, these T-handle keys are precision manufactured to tight tolerances for an exact fit. Made of hardened steel, they'll last a lifetime in your tool kit.
    Black-Oxide Steel—The dark, matte coating offers minimal corrosion resistance, so these T-handle keys are best for dry environments.
    Ultra Grip—Designed for maximum comfort and slip resistance. The plastic coating and textured surface reduce strain and guarantee a secure grip, even when working with wet or oily fingers.

    Turn screws at an angle when you can't access them head on. These T-handle key sets have a ball tip that engages the drive with less contact than a straight tip. They're handy for reaching screws in corners and underneath large machines, such as lathes and CNC mills. However, ball tips don't grip as tightly as straight tips and may strip threads if you crank them too hard. The highest-quality T-handle keys you can find, these are made of hardened steel to last a lifetime in your tool kit.
    Black-Oxide Steel—The dark, matte coating offers minimal corrosion resistance, so these T-handle keys are best for dry environments.
    Phosphate-Coated Steel—The dark, matte coating resists rust in most wet and outdoor applications. However, it won't hold up to salt water and chemicals.
    Cushion Grip—Avoid sore, blistered fingers when completing lengthy projects. These handles have a plastic coating that absorbs pressure for extra comfort.
    Ultra Grip—Designed for maximum comfort and slip resistance. The plastic coating and textured surface reduce strain and guarantee a secure grip, even when working with wet or oily fingers.
