Norvel .061 Carburetor Spraybar...Thread Size Information Wanted

The spraybar threads on my Norvel .061 Revlite Engine got messed up. I need to clean up the threads (replacement part is not available) and find a nut to hold on the throttle level...see photo. Does anyone know what the tread size is?

Thanks,

I measured my 0.8 (.049) one at 4mm x 0.5 pitch. Likely the same.

It is, I believe, an M4 fine pitch thread -- this would be M4 x 0.5 size. The standard pitch for M4 fasteners is 0.7; standard pitch for M3 is 0.5. The thread pitch matches those of my standard M3 screws.
A quick check on standard and fine pitches for M4 screws is 0.7 and 0.5 respectively.

You can find fine pitch nuts on eBay and McMaster-Carr.

Hope this helps.
