Snapped rotor bolt

karakoram

Hello, I was fitting a new disc to my wheel today when the head snapped off one of the bolts when tightening it. I removed the rest of the bolts and the disc but am now left with the thread of the bolt stuck in the hub. What can I do to remove it easily? Thanks

is there any bit sticking out? if yes cut a slot and use a screwdriver.

No drill a hole down the center and then put something in the hole to grip the sides and unscrew.

If the thread stands proud of the hub, cut a slot into it with a hacksaw blade and use a screwdriver to remove it.

You can soften up the threadlock by pouring boiling water over the remaining thread too.

Yeah the thread is sticking out so i'll try and use a screwdriver as suggested. Thanks

Get a good set of pliars and grip it and un screw try this before putting a slot into it, it should not be too tight, warm the thread with a warm air gun or hairdrier to loosen the lock tight before you do this, Clean the thread before fitting a new bolt and use a torqe wrench when tightening . Good luck

Its a dog eat dog :twisted:

I agree with Billyounger, I'd try to grip what's left first (small mole grips are ideal), then I'd try slotting, and finally drilling and using an E-Z out.

You were very lucky that the head sheared before the threads stripped. Remember, hubs are made of aluminium.
