Need Some Advice On A Rounded Bolt

[rundell]

Ok well when i went to change my head gasket i rounded a bolt near the front near the coolant pipe and just seeing on what is the best way to get it out i was thinking grinding or fileing two flats on each side and doing it with a wrench. ANyone have any helpful ideas??

 

cheers rundelll

Buy a Metrinch socket. They grip on flats, not on corners. Thats what I use.

Hmm any idea where to buy one of these? and is it just a socket to go on any wrench or do you ahve to get a certain set? cheers

great no tool place has those sockets :y: oh well might bring out the trusty angle grinder and cut bolt off then use pipe wrench. to get bolt out once heads off

Try drilling a hole into the centre of the bolt than use a hammer to place an allen key in the hole.The allen key will wedge itself within the rounded hole allowing you to turn the bolt.

Yeh i was gonna do that but instead use easy out screws but beacause the bolts in tight it wouldnt work or rip the tread or something

Vice grips.

yeh tried that seen where the front head bolt is thoght not much clerance :bash: this is on a 4k.

 

So far my desisions are try carefully angle grind the top off the bolt then use pipe wrench when head off to undo. Or mate came up with good idea to find a nut that will fit over it then use a socket to get it off

[rundell]

Or if anyone knows where to source one one of these metrinch sockets in adelaide???

i got a set of metrinch at Blackwoods, there is a shop on south rd at regency park just behind CBC bearings!

 

cost about $110, Best things you will buy! 24 spanners fits 74 different size bolts i think?

 

but they are spanners, not sockets.. not sure if you can get the metrinch sockets anymore?

Try getting a socket the next size down from the bolt size and smack it with a hammer until it fits....

Might wrk......try using a old socket or one you don't use cos it might brake :bash:

hey this hapend to me on saturday what we did was got a hammer and cement chissel n make like chunks into it so the vice grips GRIPPED then it came out easy

[Redwarf]

Someone like Blackwoods should have them. You just need a standard ratchet to ise them. I've also seen them at Bunnings, but I don't know if they stock them now....

weld a nut to the head of the bolt, filling the inside of the nut with weld. then use socket to undo nut.

 

also tighten the surrounding bolts of the f@$ked one to relieve pressure on it.

 

always undo head bolts in sequence, and use a six point socket (like an impact socket) where possible.
