one way to get them off if there not too tight would be to use a mig welder and weld an extention onto the end of the nut ,then try to remove it , i have had to torch some off and use a air hammer before on trucks that people have lost there sockets .good luck mike

 

i've had good luck with using a 12 point that comes close and a hammer , ive also ground out a socket to round and used a mig to weld in splines inside (built up with just weld).

Thanks guys for the advice, i have found a site that does 7 point lug nut key. so i will get a set of them shipped from the states as they arnt availible in the UK. Hopefully fingers crossed they will work! Otherwise it will have to be a get off however I can by the look of things.

 

you know right after you get them off you will find the correct socket , like under a seat or something.good luck.mike

 

Found the company that makes them and they are out of business. So it looks like you have your work cut out for you.

thanks for that even if was a bit if bad news!
looks like ill just have to get heavy with them!

thanks for all your help guys.

 

Snap-On sells some special sockets for removing locking lug nuts. I have a set. You might try some auto repair shops around you to see if they might have the socket they could rent you. Maybe call a Snap-On dealer if you have them and ask him if he has sold any and maybe he could tell you what shop has them.

 

Those are spline drive lugs (aka: tuner), you should be able to get a cog from anyplace here in the states that sells spline drive lug nuts.
