I use it for rear diff drain plugs on Subarus (and I hear nissan has the same type of plug). It's a 13MM recessed square aluminum drain plug, and most people just put their 1/2 drive ratchet in it and strip it out. You need to use the 13MM square drain plug tool (which is non impact, and using an impact on these diffs can crack the diff cover if the drain plug is stuck...which they always are). I bought my 24" SLX80A specifically for this job and have been able to remove every single one! You can't use a breaker bar on these, because the plug being a 4 sided plug, you have 4 ways to position your breaker bar, and it often is impossible to get the 13MM tool in there with a fixed breaker bar in any of those 4 positions (would be easier if you had a lift). Never been able to do it with a 18" bar either.
Yep, I've done several of those diff plugs, always with an 18" breaker, vehicle on ramps...
