Model T Ford Forum: Forum 2018: Size of nuts on ammeter

I have an ammeter that may be 1926 vintage. It is missing one of the nuts. Lang's say that the repro ammeters use a different size nut and don't have any to fit old ones. Before I run out to a hardware store looking a nut or, worse yet, strip the threads by trying to force on a nut of the wrong size, I'd like to know what size I should ask for.

First you will have to identify the ammeter, as Langs does have the standard nuts for a 1926 unit, as I have bought some and they work.

They are the 5016NUT Part Numbers.

The thread appears to be a #8-32 on the ammeter I have handy.

I tried #8-32 nuts but they seem to be too small. Attached are front and rear view photos of my ammeter. Perhaps someone will be able to identify it.

Thanks,

Tom

I'm sorry I can't help on the size of the nuts needed on the ammeter. I just had to post because I was distracted by a sneeze as I was reading the thread title and thought it said, "Size of nuts on an anteater" :-):-)

The large face script ammeter posts are threaded 10-32. Have several brands, Sterling and Onan and all use the same hex nut.

Tom, your 1926 suggestion threw us off.

Langs knew which one you had for some reason and they were correct, as usual.

I tried a 10-32 and it worked, without me stripping any threads.
