Rounded bolt!

Hello

 

I hang my head in shame - for I have rounded a bolt.

 

Without a welder, how would one get it out?

 

It's a 13mm, I'm thinking of holding a 12mm socket on it, spraying some black paint through socket to get the shape and then filing to match.

 

Is there an easier way? I brought some special sockets but they didn't work!

If you have good enough access you could drill out the centre and use a bolt extractor, eg; Screw & Bolt Extractor Set 5 Piece - Toolstation ....when you've got a wiggle out of the bolt spraying PlusGas penetrating fluid should help.

 

As an alternative you could try wacking a blunt chisel (a sharp one will just slice off the head!) on the edge of the bolt in the direction you want it to turn.... if you get a wiggle use the PlusGas as above. Drilling out the centre of the bolt can also help in this scenario.

 

Are you sure it's a right hand thread?

cheers, steve

 

p.s.... no need to hang head in shame; garages deal with the same on a regular basis.

A half inch socket is slightly smaller than 13mm, if you can get it started on the bolt then hammer it on, I have in the past managed to get the socket to cut a new hexagon by grinding the socket so it was sharp on the leading edge. Mind your eyes whilst belting sockets!!
