Rounded Screw - again

May 29, 2006 9 Replies

Attacked the screw with the drill. Eventually got the head off and took the handle off to find a bent door.



Anyway, I've cut a slot in the top of the screw, and it won't budge. Bar plus gas and belting it with a hammer, both of which I've tried, what can I do?


Heat, the little oxy/mapp gas torches are very good.

I've got a blowtorch. It gets hot. Never seemed much cop at shifting stuff before, but that was on agricultural machines. I can give it a go.

How much thread is exposed? Can you get two thin nuts onto it? If you can, do the top one up REALLY HARD while holding the bottom one still, then use the bottom one to unscrew the shank. It sometimes works.

Its the oxygen that makes the difference. Or try welding a nut onto the end.

Where do I get one of these beasts? Not seen one before - basically you're talking a little gas axe?

Bah. Not cheap. Tempted to try a can of the freeze stuff from the local factors...

Any decent toolstore. Welding a nut on's cheaper.

I have a feeling that might be a tad difficult. The screw is only about 3 or

4mm across. I'm not a welder but that sounds like it'd be a bit tough.

It's guaranteed to get it red hot :-)
