    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.
    Chrome-Plated Steel—The chrome plating resists salt water and chemicals better than other finishes and is less likely to wear off. These T-handle keys have the brightest, shiniest finish we offer to stand out in your tool box.
    Cushion Grip—Avoid sore, blistered fingers when completing lengthy projects. These handles have a plastic coating that absorbs pressure for extra comfort.

    Cushion Grip

    Crank screws in large, heavy duty 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. They're made of hardened steel or stainless steel to last a lifetime in your tool kit.

    Image of Product. Front orientation. L-Keys. Angled-Drive Ball-Tip L-Keys.
    Turn screws at an angle when you can’t access them head on. These L-keys 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.
    Alloy Steel—These L-keys handle high torque without bending or breaking, so they’ll last a lifetime.
    Long—The most common option, these L-keys have a balanced length for everyday reach and torque.
