Ordering by number: this is 470W254304, the Chicago Pneumatic stud. This holds the assembly together under impact. Torque and thread condition matter more here than on static equipment.

If you are working from a machine rather than a part number, start at the full diagram library, or send us the model and serial and we will match it. Machines themselves are on the Chicago Pneumatic tool range. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
