stuck nuts

[osh]

Hi All

I need to undo some nuts that have become seized, and also appear to be a little bit rounded. I have been soaking them in a penetrating fluid, but Just wondered if anyone has any tips for removing stuck nuts?

If I cannot undo them, am I going to have to get a splitter, and crack the nut off that way?

A good soaking in WD40 then undo with a Stilson wrench. Or you could try heating the nuts first.

I'd agree with dilligaf except to say that since you've already soaked them in penetrating fluid and since the shoulders are rounded, I'd heat them with small propane torch (assuming they are accessible) and use a pair of what we here in the U.S. call Vicegrip pliers (seen here: http://www.tylertool.com/vis7wr7locpl.html ). They are already ruined so will require replacing...

If all fails you can buy a nut splitter for just a few �� that will slit the nut enabling very easy removal http://www.northerntool.com/images/product/ima ges/150244_lg.gif

What size nuts are you talking about ? Splitters are for big time stuff like 12mm or more. If smaller, try using a hacksaw to cut the nut on it's axial plane and then use a cold chisel to drive it off

Ta for the replies everyone.

It was for 13mm nuts. In the end I used a Dremel. Even then the nuts where frozen solid!!!

Just replaced the nuts and bolts afterwards. I got fed up of working them back and forth!

Well done! Pleased to hear you solved your problem.
Remember in future to look after your nut a bit better. I have suffered from stuck nuts before, so now I usually lubricate them quite frequently

In the dim, distant past I restored old cars, and I applied a compound called COPPERSLIP on the thread of all bolts during assembly. It coats the thread with a film of copper , preventing seizure due to corrosion. There is another product based on aluminium, and both should be available at any decent car accessory shop. I can assure you it is effective
