Buggered is just an english mannerism meaning something off or tampered with. Can you take a photo of your lug nuts, maybe they're not original or something weird?

 

I understand the literal translation, just curious in the mechanical sense, because I'm 100% positive my lugs are 28mm. The 28mm fits perfectly snug on the lugs, and the 27mm is way too small. I'll take a pic tomorrow and post it up. But I'm pretty sure I've read other posts where people's lugs were 28mm.

 

The issue is that the caps try to rotate on the lug nuts if you use the wrong socket, like a 12 point or one that is too large. When they rotate a little, they flare out, and from that point on the 27mm won't fit easily. I think the hammering action of the impact gun amplifies this problem. I used an impact on one of my lug nuts recently while removing it, and it kind of got snug in the 27mm socket.... it took a little persuasion to remove. From that point on, I just used a big harbor freight breaker bar.

The caps are replaceable, but they are still too expensive... they only save you about half of what the aftermarket lugs nuts at britishpacific cost.

I'm in the same boat. My lugs look perfect. But the 27mm is too small. Doesn't even come close to getting over the lugs. My independent rover mechanic friend told me 28mm. He has worked on my Rover for years before I purchased it. haha maybe he told me 28mm because he had done some prior work with an impact and knew the correct one wouldn't fit anymore...

 

Don't know what to say, but a picture is worth a thousand words (I've used this socket for over 15 years) The difficulty with these lug nuts is the tin(or whatever it is) cap over the top of the actual nuts. They are soft and easily deformed. One hit with an oversized socket and they get stretched and twisted.

 

i had to get a new set recently. one factor that can cause the warping - i'm told - is that water gets in there between the cap and the lug nut. i guess after time it can warp the tin cap or whatever.

the impact or incorrect tool explanation makes more sense to me, but figured i'd share what i've been told in case it helps anyone.

 

No, not a safety issue, unless it prevents you from correctly torquing them.
It's just the metal caps that become deformed.

For those with caps that look fine but must use a 28mm, either they are expanded from rust under the cap, or their are some odd-ball size lug nut.

 

I just noticed that rovahfarm is selling D2 lug nuts for $5.60. That's just about the cheapest I've ever seen.

Thanks for that. Just ordered a new set for $133... not bad seeing as AB is a little less than twice that.

 

Anyone have any opinions on these? Look too good to be true...
