@abidou1999 The bolt wasn't new, but not dirty or rusty either. I think it was overtightened and snapped. There are other methods, just showing one.

What size mm bolt was that you removed??? becasue I over tightened my clutch to the flywheel and the bolt head snapped off! As my bolt is quite small. Thanks,

@GoogleG11993 This vid was a 6mm.

where do you get a punch like that



[90gtvert]

@grenman20 They aren't too hard to find. Home Depot, Lowes, Harbor Freight, Sears. Search for "spring loaded center punch" or "automatic center punch".

Bolts do not always break off with a flat or concave surface. Sometimes there is a 'mountain' of metal preventing starting a drill in the center. I have used a Dremel tool with a pointed diamond bit to carefully flatten the 'mountain' and to start the center hole for the bit. I also use left-handed drill bits. Sometimes the action of the drill bit turning counter clockwise will rotate the bolt out. I am an expert at breaking bolts, so listen to me!

@shsmustangs hey did it work on your broken cylinder man?/

[bmwnasher]

Those things will not work on a rusty or tight bolt BEWARE if the easy out breaks your in trouble.

Another thing that works if you don't have a screw extractor.. Drill a hole in the center that's about 2/3rds the diameter of the bolt.. Take an Allen key (Hex Key) that's slightly larger than the hole and tap it in with a hammer... Works almost every time and it's easy.
