Milwaukee Jaw Pusher Spring
Model Number: 40-50-2555
The Milwaukee 40-50-2555 is a genuine OEM Jaw Pusher Spring for use in compatible Milwaukee blind rivet tools. The jaw pusher spring is the internal spring that pushes the jaws forward within the jaw housing — maintaining the jaws in their forward-engaged position so they are ready to grip and pull the rivet mandrel when the trigger is activated, and returning the jaw assembly to the forward position after each mandrel pull stroke to prepare for the next rivet cycle. Correct jaw pusher spring force ensures reliable, positive jaw engagement with the mandrel on every rivet cycle. A broken or fatigued jaw pusher spring that fails to return the jaws to the forward position causes missed mandrel grip events and incomplete rivet sets, requiring replacement to restore consistent, reliable rivet tool operation.
Using a genuine Milwaukee OEM jaw pusher spring ensures the correct spring rate, wire diameter, and free length for the jaw mechanism it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct spring for your specific unit.
