Ryobi from Home Depot ... I realize it's a reverse thread.
Ryobi supples two wrenches and there seems to plenty
of torque. Still under return for 45 more days but I hate to
return an item this expensive because someone overightened
the nut at the factory. If I get the nut off will I have damaged
anything? ... I mean if the damage isn't obvious. Is there any
damage done from overtightening in the first place?



Put some Liquid Wrench along the nut and give the area a few taps (on
an area that wont be damaged) with a small hammer. I'd call Ryobi
customer support first--their solution is probably best. You may have
a damaged thread.
