T.McMillan Posted July 4, 2007 Report Share Posted July 4, 2007 i had same problem, what i did was, get a drill very sharp thats slightly bigger than the thread size only by 1mm or 2mm then start to drill carefully and it takes the head off then use a small drill to make a tiny starting hole, and use a screw extractor and it will take the drilled bolts out, youll find a screw extractor nearest hardware/B n Q place, or u can just use a screw extractor and ignore the first bit.tom Quote Link to comment Share on other sites More sharing options...

Dan6061 Posted July 4, 2007 Report Share Posted July 4, 2007 Cut a slot in the head and use a flat-headed screwdriver. Quote Link to comment Share on other sites More sharing options...
N Roach Posted July 4, 2007 Report Share Posted July 4, 2007 Dont drill the heads if u want the disk mount on the hub. I had this problem. If there is enough to grip on the bolt, then try some big mole grips (should work with some force) Or u could try a star key to undo the bolt, works with smaller bolts so i cant see why it wuldnt work for this.CheersNafan Quote Link to comment Share on other sites More sharing options...
paolo Posted July 4, 2007 Report Share Posted July 4, 2007 Cut a slot in the head and use a flat-headed screwdriver. Carefull not to cut the rotor, works well. Quote Link to comment Share on other sites More sharing options...

Greetings Posted July 4, 2007 Report Share Posted July 4, 2007 Cut a slot in the head and use a flat-headed screwdriver. That works very well, don't use a drill or grinder, you'll probably end up with a bigger mess than in the first place. Quote Link to comment Share on other sites More sharing options...

Don't get me wrong, I'm sure it would work & all but I reckon on a bolt that small it would be a bloody nightmare. My day job is in engineering & so far the smallest bolt I've used an extractor on has been M6 & only then because I couldn't cut a groove in it.A vice-grips (Mole-grips) on the end of the bolt is the way forward for me. If you crush the head then grind it back, remove the disk & hacksaw a slot in the remaining bolt for a screwdriver.And when you're replacing the bolts don't use the shitty wee bolts that come with the disc, go pick up a few wee stainless bolts in a hardware store. Cheaper than your lbs & by far a better choice. They'll never round off or corrode. Quote Link to comment Share on other sites More sharing options...
