I suppose that the head size matches the lug bolts/nuts so that you can loosen it with the tire iron, saving the expense of supplying a separate tool for the skirts.
The 54-55-56 owner's manuals that I've previously downloaded all advise that (WRT to "Changing Wheels"):

...the wheel shield is removed by removing the screw at the rear of the shield using the wrench furnished in the tool kit.
Yet, when it comes to removing the hub cab, the owner's manuals refer to a:

combination wheel wrench and jack handle
...as if to distinguish that from the aformentioned wrench for the skirt screw (bolt).
If you check the parts books' Tool section, you'll find a "spark plug & fender shroud wrench" listed (Gr. 16.011) separatley from a "jack handle & wheel wrench" (Gr. 16.012). IIRC, that spark plug wrench looked similar to what you used to find on a card and hanging on a hook in gas stations, convenience stores, and discount department stores. Yet, I also recall using the lug wrench to R&I the skirt bolt on my V8 cars.
However, both of those tools show the same P/N, respectively, for 22nd through 56th Series, which - at first - seems to run counter to the notion that 55th-56th Series fastener had a bigger head.
Is it possible that the spark plug wrench was stepped to fit more than one size of hex? Is it just dumb luck that the lug wrench fits the skirt bolt as used on 55th-56th Series?
