Yeah any hardware store that has the pull-out trays of specialty parts should have them. Most antenna stuff is 3/8x24 fine thread, not the more common hardware 3/8x16 coarse thread so be careful.

Unless it's Chinese antenna stuff which is often 10mm.

Assuming  they screw in & not attached to studs, the cheapest I've seen are bicycle axle extensions for training wheels on amazon.  The ones I bought last are out of stock, but looked like these.  They do reference a 3/8-24 thread. $9 for two.
Amazon Product
  • Upgraded Material: Made of 304 stainlss steel, which is More sturdy and durable ,corrosion-resistant and long-lasting .


Verify thread size & pitch with vendor to be sure. Return if they don't fit

If they are just coupling nuts, those are cheaper & easier to find.

Five packs on amazon for $15. I got one a few years ago and I'm still working down my
inventory.
