removing rusted cat bolts

[Topgeartom]

Well yesterday i decided to pop on my short shifter, but when i got underneath the car could see that the bolts holding the cat on to the rest of the exhaust were rusted solid. They didnt even have much in the way of edges to get a socket on, i tried a few different sizes and they all just spun straight round.

Is there an easy way to try and shift them?

I dont have an a grinder but even if i did i dont see where you would cut them to get them shifted without damaging the flange.

Answered your own question there really if sockets are spinning and rounding the bolt. Will need to be cut off carefully.

have you used them yourself?

 

[justinhincks87]

ye they are a wicked piece of kit..... you can even tap them over allen key bolts and it grips !

i use them quite often as im a mechanic by trade

Might have to invest. The bolts are pretty far gone so it might be the only way to get them off. Thanks man.

you can heat them to loosen the bolts so i have been told by a garage

cheap grinder from B&Q's probably only £20 and is a handy thing to own
