It is the same size bolt head as the lug wrench, which you also need to
change the tire, so a smart design decision. What is dumb is letting
some tire jockey over-tighten your spare tire door bolt with the same
air wrench you let him over-tighten the lug bolts with.

I tried WD40 but its real diffuicult to apply it and so far it refuses to yield and the socket continually slips. Anyone got any ideas? Personally, I think the whole concept of needing a special tool to access the spare tire is a dumb design.
