Milwaukee Torque Key
Model Number: 43-96-0012
The Milwaukee 43-96-0012 is a genuine OEM Torque Key, a small, precision metal key that transmits torque between two rotating parts inside the tool. A drive key like this seats into a keyway machined into a shaft and the mating component, such as a gear, spindle, collar, or clutch part, and locks the two together so rotational force passes through the joint without slipping. It is the mechanical link that ensures the shaft and the part it drives turn together as one, transmitting the tool's torque where it needs to go. Manufactured by metal injection molding for a precise, consistent shape, the key must fit its keyway exactly to carry torque reliably. Though it is a small component, it does a critical job: a torque key that is worn, sheared, or deformed can no longer transmit torque properly, allowing the driven part to slip on the shaft, which causes lost power, play, or a failure to drive. Replacing it with the correct genuine Milwaukee OEM torque key restores a solid, slip-free torque connection.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, and because keys are specific to the exact shaft and keyway they serve, always verify your tool's serial number against the official Milwaukee service parts diagram before ordering to confirm this is the correct torque key for your tool. Do not order by appearance, since keys that look similar can differ in size and profile, and the diagram is what confirms the correct part. A sheared or deformed key should always be replaced rather than reused, and it is worth inspecting the keyway in the shaft and the driven part for wear when replacing the key, since a damaged keyway can shear a new key. The shaft, gear or spindle, and any spring or retaining parts that work with the torque key, such as the torque key spring, are separate parts that vary by tool, so refer to your tool's parts diagram for the correct companion part numbers.
