therad size on jets

What is the thread size of. Holley and AVS and AFB and thermoquad jets. THANKS

check me on this; holley 1/4-32, carter 5/16-24.

I'll try and check mine, both brands soon, there in the race trailer and there are 5 inches of snow in the driveway now and I don't have any boots or shoes that I can use to walk out their today, it should be all melted by tomorrow afternoon or by Friday morning
I'm thinking the Holleys jets are either #12x? or #10X?, no idea about the Carter and Eddy brock jet sizes

1/4-32 sounds right to me.

I had a machinist buddy make some extensions for some Carb Shop metering blocks and I believe that's what they had to be threaded.

Although I don't claim to be an expert.

Holley # is 122-XX
Some Rochesters are ¼-28 NF

did a little internet search and the holley is 1/4-32. i knew for certain it wasn't 1/4-28. i have used a 5/16-24 to clean up threads for carter afb jets.

years ago, i made a variety of jets for a thermo-quad, and they were 5/16-24 thread.
i kept the program for those , but alas, the machine i made those on are super obsolete these days.
