Stud Bolt for Jet Nozzle?

[TomDavies]

I just ordered a new Left Jet Nozzle from eBay, but it doesn’t appear to have the stud bolt on it. Im not even entirely sure it’s a stud bolt to be honest - I tried to remove the one from my broken nozzle, but it snapped. Does anyone know the dimensions for it?
The nut is a 1/4 inch elastic stop.



Thanks.
