Rounded Nuts

[Toby_Smith]

Alright then guys n gals.

Which one of you wants to give me some advice on how to remove a rounded nut?

It looks like the previous owner of my bike has had an ill fittin spanner on the nut which connects my exhaust bracket to the frame and rounded the f**ker right off.

Is it worth me getting a bit of WD40 on it and having a go with a set of mole grips?

Cheers

That'd work. First thing though, take a wire brush to it and remove any crap. Then see if a smaller socket will go over it. A favourite trick is to belt over an imperial socket onto a rounded metric one...

If all else fails you will have to invest in a nut splitter, pita to use mind and I prefer cutting the buggers off and replacing whatever it is I am working on.

is it the nut or a bolt/stud if bolt cut a groove in head and use a screw driver

WD40 overnight + mole grips is the usual first attempt. If you can heat it without damaging anything else, then that's worth a go too. Maybe try filing flats onto the sides then using a smaller spanner?

That's what I've done more than once! I like the welding idea as well, if I had a welder that's what I'd do!

dont use WD40 its a water dispersant, pop down to halfords and get a shock and unlock spray

then hammer an old socket over the nut and undo, it helps to strike the socket head whilst applying pressure in the direction you wish to turn.. or get a long handled socket bar (breaker bar...)

and remember lefty loosy, righty tighty....

Never seen that shock and lock before, does it work ok, I usually use plus gas then loads of heat either from warming the engine up, or a blow torch, which I hate using near the bike.

any motor accesory shop should have a similar product, we use a penetrating spray for rusty nuts/bolts at work, whichever name it goes by its better than WD40...

warming the engine, and hammering a socket over manifold bolts is one of BanditMania's tips

just beware of your fingers, as the exhaust will be hot..
