Ordering by number: this is P006099 (also carried as 3310103835), the Chicago Pneumatic elastic stop nut. It secures its joint against constant vibration, which is why it is treated as a replaceable item rather than a permanent one.
It is called out in the parts diagram for the CP 0112 0112S 0112EX Paving Breaker and CP 0111 CHLA 0111 CHIT Pick Hammer. Compare it to the reference callout on the diagram to be sure it is the position you need.
Everything else on that machine is one page away on the full diagram library; complete tools are on the Chicago Pneumatic lineup. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
