That’s the correct part for the drain plug, which is all you would need. The complete set of washers is at

Upgraded Lexus IS drain plug that is harder to strip: 90341-24016
 
So was doing this service. Started at the rear diff, transfer case, then got to the front diff. Tried all the tips in here but didnt want to go at it with a chisel.

Stopped by my local muffler shop since I have used them before (they are Punks Mufflers in Vancouver, WA for anyone in the PNW) and they are awesome!

Took them 10 seconds to weld a 22mm nut. Drove home and the bolt took ZERO effort. The heat and the much improved leverage obviously was the world of a difference.

Decided to order a 22mm replacement from amazon rather than that 12mm I think that Toyota/Lexus sells. Waiting on it now before swapping the fluid.

I can’t recommend these enough. I’d have a set for your next diff maintenance.

I wanted these! BUT I needed it fast since I dont want to leave the welded bolt on there and I want that fluid changed. I am hoping the amazon one is decent enough quality for 30-40k miles. Will definitely plan to get this next.

IMHO and FWIW I'd dump the Amazon sourced plug even if it meant sacrificing 1/2 a quart during change.

Yea I went and picked up a oem drain plug. its the 10mm hex but ill just repeat this process in 30-40k miles lol and make sure I order the Kaon
 
It usually helps avoid stripping. But it is possible to strip the head on that one too.. you just have to try a lot harder.
Just took both of mine off. Damn it was on there.
I sprayed liquid wrench on it and let it sit for a little bit.
Then 10mm hex using a 3/4 ratchet and all my strength.
Since I don’t have the car jacked up, I didn’t have a lot of room for a breaker bar.
 
Easier to weld on a new nut though if needed.
Did both.
Drained 1.75L and put back around 1.9L of Ravenol.
Drain plug was very easy to torque to 29ft-lbs compared to the fill. Hopefully it’s right and doesn’t leak.

The new plugs are a tiny bit shorter than what came off..

saw this on another forum. wonder if there's any truth to this..

I do think its likely that some of the 'strip-out' incidents are caused by people using a 3/8" hex driver instead of a 10mm driver. A 3/8" driver tool is visually nearly identical to a 10mm driver tool, and 'seems' to fit the recess in the plug, but is actually about .020" undersize. Given the small hex recess size, the shallowness of the recess and the high torque required to break the plug free, using a hex driver tool that's .020" undersize can be fatal.

What "we" don't read about are the situations like mine...
Yawn.
Crawl under vehicle. Loosen filler plug. Extract drain plug. Drain fluid. Yada yada.
As our Australian friends say, no dramas.
Of course, something else is gonna bite me in the butt.

I used a very high quality 10mm bit in mine and it stripped.

The issue seems to be the very large thread diameter for the size of the tool hole. Toyota did this to make the overall hole large enough to get a measuring device in there for setting up the gear lash. But that's a lot of surface area for the gasket to stick, even when it isn't overtightened.
