Apart from a hammer or door stop, what automotive jobs (or otherwise) uses a 46mm spanner or "wrench" as you Americanians might know it as?
Thanks!
Thanks!
What would you use a 46mm spanner for?

Some Ducati rear axle nuts are 46mm.

Windpower, lightpoles, and signage all use larger fasteners than that. You run the nut down by your favorite method and tighten with a striking wrench.
I would use it as wall art. It would be the only tool I ever polished.

VW bus rear axle nuts are 46mm.

IIRC, and I had one of these decades ago, the rear axle nut and engine gland nut are both 36mm, not 46mm. Nevertheless, they were a bear to remove and replace to proper torque. If the rear axle nut wasn't torqued down sufficiently, the lash in the splines would strip the splines out of the rear brake drum.
Correction:
The rear axle nut on the Type 2 (aka buses) from '64 onward were 46mm. I need to read more closely. AFAIK, all the beetles, Things, Ghias, Type 3, and buses '63 and older, etc. were 36mm.
46mm could be a size used on very large nuts holding large light poles and large bollards to their foundations. Some of the bolts and nuts I've seen on some of these have been rather large. I don't know what the common sizes are for them. Millwrights who work on the big stuff would have wrenches in this size class.
I have this 24" adjustable - it dwarfs the 12" and 10" - and I have a 50mm combination hanging on the same hook with it. They're about the same length.

You should use a socket along with a torque wrench (to install) but many don't.

What makes you think wrenches are only used in the auto repair field? Something that big (and bigger) can be seen & used in the oil industry, mining operations, refineries, factories, farm/construction/industrial equipment repair, etc

I'd probably hold it for pictures to make my hands look smaller.

Kesla log loaders (made in Finland) have their tie down nuts in 46mm hex size. Dont remember the stud size, likely 30mm.

I think some fan clutches use that size.

I’m gonna go out on a limb and say that if you don’t already know what you can use it on it’ll make a nice hammer or door stop...
As for me, I use one on Ermeto (DIN/EO) hydraulic fitting quite often.

I used to use 46 heaps for gas refinery stuff, 1 1/8 studs. I’ve used it a few times in hydraulics as well. Industrial gearbox studs, are a few examples. 46 is the standard for M30 nuts , and a conversion for 1 13/16

I think that is a size for the leveling screws on one of our Horizontal Machining Centers.

I don't think that!
Hence "Automotive repairs (or otherwise)" I mainly work on cars though.
In any event, my chance to own the old spanner/wrench has now slipped away, but thanks for list of things it can be used for.

Uhm, as per the rules of GJ you must first purchase said unknown tool then ask what it’s for.

Some E series BMW use a 46mm axle nut. But socket, not wrench.

I have bolts on the Unimogs I use a 46mm socket. The loader on my 406 uses a pair of bolts to hold it down.
Why use a striking wrench vs an impact? I had to Google the striking wrench part.

Its like impacting lugs without checking them with a torque wrench or breaker bar ... sometimes impacts are not reliable and a striking wrench is a manual force that can be seen and felt... other times the socket is not deep enough for the stud so a wrench is required for the final tightening.

I have one. They don't get a lot of use in the automotive field, but there is one job where it is essential. When you are installing a new muffler on a 1972 or newer air cooled VW bus, there are two 46 mm nuts that must be tightened as part of the install. You need that open end wrench to do it. I bought it for that task alone and I have never used it for anything else.

Viscous fan clutches on a lot of Medium and heavy trucks are that size.

VWs and Mercedes use this size for selected larger fasteners usually involving R&R transaxle on VW or other items on MB.

As a Forklift/equipment tech, I have one very large wrench and it is a Proto 46 mm. I have used it exactly twice, both times for the kingpin nut on a JLG scissor lift.
