Ordering by number: this is 430101W10, the Tamco/Toku through bolt nut. It carries the clamp load on its stud or bolt. On an impact tool, thread and face condition matter a nut that has been run down over damaged threads will not hold torque.
You will find it on the diagram for the TJ 15 Rock Drill (RD 30). That machine is the Tamco/Toku TJ-15 Rock Drill if you are pricing a replacement rather than a repair. Check it against the reference number on the diagram first; serial breaks change what fits.
Work through the rest of the assembly on the same breakdown, or start over from the parts diagram hub. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
