Yes, that's what I envisaged Mike. The issue here is there are only a couple of turns of stud thread that protrude though the thick web / boss / centre of the wheel so the well would nearly *only* be held on by any thread up the tube bit, rather than within the body of any 'nut' portion of the thing?
Oh, so the above could be correct then?
ie, If your vehicle uses alloys on studs (rather than bolts) and you were to remove one peer down the hole with a torch you would see the stud sitting it a tubular hole (the hole being noticeably bigger than it needed to be to fit over the stud) the tip of the stud just sticking out over the level of the bottom of the main part of the hole (where the nut would sit). The retaining nut you now have in yer hand would have 3 discrete sections, tubular threaded section, flat / tapered middle and hex headed head (the whole thing could be bored through and threaded).
Well, it looks like the bottom of the holes are tapered, soo, I would need some 'nuts' with the right taper and right thread (tubular bit diameter and length to match the wheels ) to match the Ford studs.
So with 16 of these plus spigot rings this cheap set of wheels isn't so cheap? ;-(
All the best ..
