    Are you able to ratchet after it reaches its max torque?
    BySep 16, 2026
    1 Answer | 
    Answer This Question

    Yes, the ratchet can be used manually without engaging the motor, so after it reaches its 35 ft-lbs max torque, you can continue ratcheting by hand if needed. ​

            Is there any potential damage to the anvil or function if I use the ratchet manually to loosen nuts by hand before using the trigger to remove the bolt? Or is it advised to use a different tool to loosen the nut and then switch to the high-speed?

            Answer This Question

            I don’t believe there is an anvil in the ratchet . It is only a ratchet , not an impact ratchet .

            By|Aug 10, 2026

              Hey, Brian. Yes, you can use it manually for light loosening, but do not exceed its torque rating. For tough bolts, break them loose with a standard ratchet or breaker bar first, then use the M12 FUEL™ ratchet for fast removal.

                    This is the 2557-20 and according to Milwaukee this model has higher torque at 55 ft lobster and lower rim 200-250 rpm than the 2567-20 which has higher rpm 450 but lower torque at 35ft lbs. Hope this helps

                        Say goodbye to hand ratchets. This Milwaukee fuel makes the job so much easier and faster. No need to swing wrench or ratchet back and forth.
