Stop Nut is the American Pneumatic Tool service part carried under part number 1280582570, previously 00129. 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.
It appears on the 190 Paving Breaker and 190A Airgo Paving Breaker, and on 4 other machines breakdown. Check it against the reference number on the diagram first; serial breaks change what fits.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts breakdown index. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
