Okay awesome. Thanks Ken. Ordering now. 

Perhaps metion that on the product page to avoid confusion 

All of the bolts on our site is listed by the shank length.  The stock bolt is 27mm as you measured.

Cheers,
Ken

Hey 6464, you know, I kinda tried that at first using a good bolt from the same wheel. But the hole was already so mangled that it pulled the bolt off axis and started to mangle it. I threaded that slightly mangled bolt into another hole to recut the thread, which worked okay. I managed to abort before doing too much damage, which is more than can be said for the first one. 

Cheers

you can make your own tap by grinding a couple of slots in the bolt. and bolt away. 

Looking at the lug bolt page to order new ones. Using my eye to compare mine to the picture it looks like I have a 40mm. But I measure 50mm end to end, 27mm shank. What does the measurement on the product page refer to? Total length?

thanks

Hey Ken, thanks for the reply. The Mini is a 2013 R56 Cooper S

im going to try to retap the hub, I ordered a M14 x 1.25 tap and see if that works. It's only the first couple of threads that are ruined. If I can get past those the rest of the hole is clean. Going to order a couple new lug bolts from here.

If that that doesn't work out I'll try the helicoil route. Although, the drilling and inserting sounds a bit more of an opportunity to make things worse. In which case I'll end up getting a new hub anyway, nothing lost but a little time, but possibly could save a lot of money. 

Either way, I think the wife will not be happy and I'll be banned from working on her car from now on

cheers

Hey Adam, 'stuff' happens to the best of us - don't feel bad.

As for repairs, there seems to be different opinions on thread repair tools such as Heli-Coil, Timeserts, Keenserts...  most seem okay with this. 

Some caution against welding and re-tapping the thread since the high heat may alter the composition of the metal making it brittle.

For the time, tools, and effort it may take to repair the thread, you might consider replacing the hub - go aftermarket if budget is an issue.... - What year / model is your MINI?

Let us know how this works out!
Ken

Please help an idiot out!

i can't believe I did this. In twenty years of tinkering with cars and bikes I've never cross threaded a bolt. But these stupid fiddly Mini lug bolts caused me to slip up. Why o why can BMW not just use studs like everyone else?

So whilst putting everything back together after doing my wife's brakes, I managed to cross thread a lug bolt and mangle the hub thread. I don't want to spend $160 on a new hub if possible so I'm hoping the hole can be repaired. Will a simple tap and die set do the job. Baring in mind I've never used one before. 

Any recommendatins for an okay hobbyist tool? Quite a few China Cheapos on Amazon. Am I better off buying just the size I need for now and get better quality, or should I get a budget set?

Finally, anyone put in a stud conversion kit? 

Cheers
