Between you and me, the Ryobi 3-year warranty stinks, but Home Depot
seems like they'll make good anyway.
I called Ryobi, at
800-860-4050, using this model P4360 diagram:

I explained the broken parts:
NUT: #24, P/N 099988002007, Hex Nut (M6), $0.83
BOLT: #6, P/N 099988002021 Bolt w/Washer (M6 x 25 mm, Hex Soc. Hd., $0.83
RING: #2, P/N 099988002022, Retaining Ring, $0.83
They told me I could order them (plus $6 S&H) from their parts guys:

But, I'm not so sure that the nut is stripped.
It might be whatever plastic is holding the nut from spinning.
So, I called Ryobi Tech at Ryobi Tech 800-860-4050x2x2, who is
researching what holds the nut in place.
Meanwhile, I called the Home Depot, which said that anything under 90
days they'll just replace, and if it's over 90 days, they'll give
a store credit.
Ryobi says that they can charge for the warranty service, which
would, for a $100 pole saw, probably be prohibitive.
