Those bumper bolts

..How do I get them off?
I mean the bolts on either end that help hold the blade to the valance, I've tried undoing them with a normal spanner but the whole bolt is turning and as one end of the bolt is round and shiny i can't get anything to grip on it :x how do you do it then?

Sad answer is that they'll have a) seized and b) worn the square retaining holes round after all this time, so however you can :( Cutting with a Dremel from behind has worked for me before

Angle grinder.

The problem you might encounter next is that because the holes in the blade have rounded the new bolts won't grip properly either, unless you're replacing the blade with a better one.

True - grinder with a slitting disc, cut the bolts and nuts lengthways, then chisel them. Sounds daft, I know, but I have had precisely this problem

Ok, thanks guys, I'd love to replace the blade but i simply cant afford to buy a new one and can't risk it with the quality of new chrome. I'm taking it off because I need to repaint the valance.

I've just had a thought, maybe I could use the angle grinder on the head and cut a slit down the middle then treat it like a screw? if that makes sense..

no reason why not, (though if the nut is really rusted-on you may not get a good enough grip in the slot) just be careful the disc doesn't run away with you and damage the blade!

Slitting the lot from the rear does work, honest :D

another answer which does work on very rusted nuts and bolts

do not attempt to undo them, instead try and tighten them more and you will find they will snap and break

job done so easy
