Damaged locking wheel nut

Post by BarryM » Tue Jun 01, 2021 6:45 pm

I've got a set of locking wheel nuts on the car and stupidly I let the 'key' slip while tightening one yesterday and have managed to damage the key. I think they might be Mcgard but were on the car when I bought it so not 100% sure.

I now have 3 fully tightened bolts and the 4th was screwed in but not fully tightened. The design looks symmetrical but as it only fitted in one position when it worked I'm guessing it's not and I really can't 'feel' what is the correct fit to try and maybe hammer the key onto one of the bolts as I think I might make things worse, any suggestions on how I get my locking nuts off to replace them?

Might be a McGard but a lot of the later BMW ones looked like that as well - first step would be to pop into a BMW dealership to see if the pattern matches one of the standard ones

You can buy sets of them - makes it easier for the low-life scum to steal your wheels

Failing that, I know that some people have had success removing rounded wheel nuts with one of this type of universal socket - I don't know if they'll work on a McGard socket but they're cheap enough to give it a try and, if it doesn't work for this, it may come in useful later

Thanks Perry, they were probably on the car from new in 2001 but I guess if I go to BMW they can either help or be discounted.

Probably not the method you want to use if you can help it but i have removed them before by getting some mild steel pipe of a diameter that just fits over the round head of the nut/bolt, and arc welding the head of the nut to the inside of the pipe down the middle of it (you need an arc welder as obviously a mig torch head wont fit down the tube)
Then loosen it with a T Bar through a hole drilled through the end of the tube. Keep the tube as short as the wheel will allow for easier welding rod access!

Something of a "last resort" method but it has worked for me before!

Thanks Marc, that does indeed sound desperate but we shall see!

I've just trawled through all the paperwork and receipts I have for the car (it's a box worth and I should probably improve my filing) and I'm delighted to say I've found the original McGard document with what looks like a code for the key type so hopefully I can order a replacement from them, I'll have a look at their website and hopefully these can be ordered in the UK.

Sounds like a result and the last resort hopefully wont be required!

Good luck with it :D

Good news for me, McGard have a simple order process for replacement locking 'keys' on their website: https://shop.mcgard.de/customer-key/ the order process is done through their german site but is quick enough and I got my replacement in 7 days.

I guess if I'd given it some thought I might not have panicked so much as the key is the softer metal of the two parts and will be damaged before the locking wheel bolts so if/when you damage a key the replacement means you don't need to replace the bolts as well. New key is solid on all 4 nuts including the one that the key twisted on so lesson learned.
