Technical Mystery wrench

I found this in my tool box box i dont know what its for. Stamped steel, 1 3/8 obe side 1 1/4 the other. Iam thinking maybe for a wood working tool like a table saw.

 

You could also use it to turn your nuts, fasteners that is.

 

Possibly for an air tool, I know my old die grinder came with a couple of stamped steel wrenches like that to loosen up the chuck, and I've seen a few old DA sanders need a big flat wrench like that to remove/replace the pad.

 

Yeah don’t loose it you’ll need it for a tool before you know it and it’s the only wrench that works for the job

 

looks more like table saw size, than die grinder size.

 

Router nut tool?

 

Made in China? HRP

 

Looks to designed for square nuts. Possibly farm implements?

 

I have dozens of those sheet metal wrenches. Come with various tools like routers, table saws, etc., usually woodworking tools.
