Hi Rich,
In your photo below, I noticed that you have apparently encountered something that I recently experienced. This observation, my theory and my proposed solution will probably generate mixed opinions, but here goes: You are obviously using an aftermarket hub extension, as I have. There are at least a couple of differences between the aftermarket unit and the original. For example, note the wall width of the splined hub. The aftermarket unit is considerably thicker.
Another difference is that the angled contour cut for the hub nuts is not the same. You will note that your original (or original-style) hub nuts do not fit snugly against the hub extension (the conical end is not cut at the same angle or depth as the hub extension). You will also observe first hand or by looking at the image that the original-type hub nuts go into the opening farther than they should resulting in little of the nut for your socket to grab.
Everyone always advises to use the "locking-type" hub nut as it offers additional safety, though I have often wondered about this since millions of american cars do not use these "locking" hub nuts, and I have never heard about the wheels falling off the axles of those cars. But, I always did what was advised. Until a few weeks ago...
I began a search for a hub nut that had a conical front-end that would match up with the aftermarket hub extension. I discovered that a Dorman hub nut, part number: 611-014 fit perfectly. This nut matches up with the hub perfectly and yields a fully available nut surface for your socket so that it is easier to securely tighten. Now, these will set you back - I think they were $1.10 each and they are hard to find (just kidding) went down to the CarQuest store where I picked up a bunch.
This brings me to my theory. I say theory because I have absolutely no facts to back up my conclusion, but somewhere along the line I have to wonder if the manufacturer of the aftermarket hub extension said, "why don't we machine these hubs to fit readily available hub nuts?" Someone on the Forum or the Healey List may know the manufacturer. I think I heard at some point but I don't remember and I don't have it handy.
Anyway, I have the Dorman nuts on my car now. They fit nicely, tighten beautifully and uniformly, and show no signs of loosening.
Well, let's see if this generates any conversation or controversy. I only attach your name to this Rich, because your photo shows the same poor fit of nut to hub that I encountered and I thought you might like to know about my thoughts on this issue.
