Rounded off bolt heads!

[theyeti]

I got a set of stud extractors off the snap-on man. They aren't cheap (about £85 for 5) but worth every penny. Much better than the LH thread ones. They've never let me down and i've not bust one yet you drill the right size hole, hammer them in and windy gun the bolt out. Brilliant!!

haven't got any pics mate, but tomorrow gonna give it a go getting them out, so we'll see. Can tell this is where experience comes into play for sure, tell you what you pay good money for tips and advice like this so this is real fantastic help guys (dont think your getting your paws on my money though lol).

 

Really is very much appreciated

if you can get at these bolts knock them loose with a screw driver or chisel to the left,anti-clockwise usually works if you can heat them first with gas or arc welder (put a piece of 3mm etc on bolt & arc weld the 3mm piece to warm bolt underneath) then knock it round

were theres a will theres away every nut,bolt etc will come out even with limited tools it just takes time

good luck

All good tips here,my bit,I think you have a cast ally flyweel/fan behind the blade assembly,lots of little taps rather than bash the grandmother out of it, cast ally is brittle.

Give it a squirt of WD 40 or similar a few hours before removal.

If you have some oxy/acetylene at hand then jobs a quick un, if not try as above with a larger allen/star drive. Give the thread of the bolt a scrub with a wire brush and a good soak in plus gas.

 

If all else fails and you aint much at hand, lots of hits with a lump hammer and a cold chisel to break the nut will do it. Will take ALOT of effort though.

Ooops forget my hammer bashing if it is an alloy flywheel:blushing:

 

Nut splitters instead maybe.

Option 1 (as others have said), batter a good TORX bit into the mangled Hexagon hole and apply pressure gently and incrementally.

 

If that doesn’t do the trick drill into the hexagon with a drill bit (use a decent one) of that size or slightly bigger. If the bit is bigger the head will start to spin as you remove the material connecting the head to the shaft. If the drill bit is smaller, judicious application of violence with a chisel will separate the head from the shaft.

 

Once the head is removed the threaded portion will usually wind out with a minimum of effort.

:try knocking a torx drive bit in the bolt head, if you can give the bolt head a good belt with a hammer and drift first and then it should come out

how long ago did you get these as i have a set my self but they are geting a bit past it and mr snap-on says you dont get them any more

knock a slighty larger torx (star drive) bit into the all an slot, it will cut into the edges of the hex then wind them out

 

As above but don t use a ratchet. use a tommy bar and hit tap the back with a hammer as you slowly turn the bolt
