I tried searching but it returned with this error..

Erreur Sphinx : connection to localhost:3312 failed

Merci de contacter un Administrateur !

Anyway.. I rounded off one of my wheel nut and now can't get it out. It's one of those hex type wheel nut .. and the inside of the nut has been rounded so the hex key can't grip onto it.

Any idea on how to take it off? Or should I just try to pump up the tyre and drive it quickly to a mechanic? It's got a small piece of metal stuck on the tyre making it flat.

you may be able to (depending on how damaged the hex is) go to a tool shop and by the next size up allenkey socket attachment, so if the original one is 10mm you should be able to buy an 11mm one, maybe even a 10.5mm one. and then just use a hammer and hit it into the hex, make sure its in there real good then use a breaker bar to turn it.

bunnings didn't have it.. they don't have allen keys this size, only smaller ones.

guess I gotta wait till tomorrow for other shops to be open to get the bigger allen socket.

those allen key with the bend doesn't seem to come in sizes this big I think..

just limp it to a mechanic, it can be their headache.

if you can fit a larger hex key in the centre (smash it in with a hammer) or a socket over the outside (same...hammer) that might work. But if its already stripped it may well be too tight.

if all else fails a good workshop can weld a good nut on and unbolt it.

BTW send the bill to the tyre shop that last did it up and ask why they don't use a torque wrench to do up wheel nuts like the workshop manual says

Hammer and chisel it out.

Or what Duncan said "a good workshop can weld a good nut on and unbolt it". Your mechanic could help you out there.

BTW how did you round off the nut? Did you use a rattle gun and blasted it in?

Well... I guess it was used by a rattle gun to tighten it in when I had my tyres replaced last time.

Couldn't be f**k doing anything in this heat so I just went and buy a portable air compressor and sit there for like 15mins letting it pump some air in the tyre. It wouldn't go pass 20psi and you can hear air pissing out. So I just drove it to the closest tyre shop and he got it out for me. I didn't watch him as I had to go back home to get my allen key socket that i forgot at home but it look's like he used a chisel with a hammer to get it out. Only charged me for a puncture as well.

I guess I was too paranoid to use the chisel and hammer cause I might miss and damage my rim. Ended up changing every nuts on the car as well as I don't want this to happen again and stay clear from rattle guns when putting them in.

Cheers for all the help.

^^Yeah all good then if the tyre place got it out for you.

In future, I use a wheel brace to tighen up the nuts and all done by hand.

This happen to me before when a tyre place replaced my tyres for my Lancer. The rattle gun cracked the bolt then over time water got in and rusted the bolt, went to get the bolt out, it rounded.

Now its all by hand or take it to my mechanic who does it all by hand.

    • Nah its a server spammer thing  Although, now that I manually approve all the accounts I can probably loosen up some of the restrictions.  
    • Thread bump, again! Although, no bad news this time. Posting for the sake of possible root cause. Basically, I rebuilt it (mostly stock), installed Haltech + sensors, had it running fine on new ECU.  Still not really understanding why it cracked pistons last time. Got to tuners, and while checking timing, noticed +-10deg of timing scatter while revving. Changed CAS, and it was rock solid. While not definitive, can't imagine seeing 20+ psi with that amount of scatter would be a good thing. Also glad I found something.   Bit more of a run down; Carried out a stock rebuild, a set of stock pistons, out of a spare bottom end. Everything stock apart from head studs and oil restrictors. (so I can pretend I didn't let the Nissan out, ha.) Armed with the measuring gear and FSM, set about doing overhaul. Oil restrictors as per oil control thread for a RB25, stock oil pump, drifting. Head drain/vent from rear of head, to passenger side of sump above oil level. Two dash 10 vent lines from drivers side of sump (unused atm) Hi octane style cam cover breather kit Splash covers over last 2 cam caps. Both breather lines from cam covers to vented to atmosphere catch can, not plumbed back into sump (wanted to see what it was actually breathing). Got it run in (did about a 1000km) no to low boost scenario, As I had questions over old ECU setup. Installed haltech +sensors for flex Retune on E85 (finding CAS Issue along the way), made 300rwkw at 20psi, out of wastegate. Did a drift day the next day (yes, it was a big weekend!) and was checking catch can throughout the day, ZERO blowby. I mean nothing. Lines from cam covers are not even wet. Done a bunch of street driving, spirited and catch can is still dry. Early days I guess, but pretty happy so far. Also now run 10w60, up from the 10w40 that I used to run. Oil pressure is significantly better, especially when hot (as you would expect)      
    • Thanks buddy. I thought it was a server storage thing. 🤣
    • Perfect! Thanks for this, both look like great options!
