Which nut is best?

[Gazz]

This thread is technically NBR but lets not split hairs.

I've basically rounded a bolt head on my car and have tried various methods to remove it. Tried welding a nut onto the end but that also rounded.

So I'm wondering if there is a certain type of bolt that I could use, perhaps with better metal properties or alloy to prevent it rounding?

P.S - I used a partially rusted nut that was lying at the bottom of an old toolbox. Probably wasn't the best idea but that's all I had available at the time.

Are you using a 6 sided socket or one of the 12 sided ones?

Its a pincher bolt holding in front shock absorbers on an 15 year old Ford Mondeo.

I have 6 sided and 12 sided sockets and spanners.

Nothing holding it in from the other side.

Here is a tutorial on youtube. The bolt in question is at 2m12s in the video.

Take a large hammer and beat the living shit out of the end of the bolt.

A quick tip for next time....

I use bottle jacks to remove stubborn suspension bolts. Won't help with a rounded nut, but might have stopped it getting rounded in the first place.

I put a decent socket or spanner on the bolt so the wrench is almost horizontal and pushing it up would undo the nut. Put the bottle jack under the other end of it and you can safely and slowly put 2 tonnes of pressure on the nut.

Never failed me yet.
