Ordering by number: this is 470W224539, the Chicago Pneumatic stud. This holds the assembly together under impact. Torque and thread condition matter more here than on static equipment.

Give us the model and serial off your machine and we will confirm the fit; the parts breakdown index and the CP tool catalog are the other two places to start. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
