Hi Doug!

The Trailer Spare Tire Mount by Dutton-Lainson # DL22128 does indeed have 1/2-20 threads. I included a diagram with all the measurements you could ask for as well. This also fits 8", 9", or 12" wheels and 4 or 5-hole rims, if you needed to know.

What are you planning on using this on?

thanks for the information. Exactly what I needed. I purchased a duralock safety lock and it only works on 1/2-20 threads so needed to understand if I could replace my current spare tire bracket and it would work with my lock.

@Doug Had a feeling that was why you were asking. I will mention that you may need to cut the threaded section down a bit to get the DuraLock to thread all the way down, but I can't say that for sure.
