Can you get vice grips on it?
Weld a bolt to it, the heat will help "break" the grip of the thread
Use a metric or Imperial allen key,slightly bigger, and tap into the cap.
Lubricate over night with Inox/RP 7. Best mix I found is half acetone and half ATF, (trans fluid)
Grind it off and paint over it!! Ignore that....
Tap socket over the head, (Tight fitting one) Impact sockets are best.

Any one else???

When i said recessed i meant recessed as in Yammie XS650 side oil filter cover. Bolt head is level with alloy cover so can't grip nor get any lubricant onto threads nor cut into bolt head !@!#!!@@!!!!

Aside from a good hard 3-5 wacks sith a heavy hammer, drill the head off, get the cover off and then get remains of bolts out with a locking wrench or weld a pied of bar across them.

Try a crew remover, they can be bought at the hardware shop, they screw into the screw, or bolt and in a reverse thread. so you can then unscrew the bolt.

i'd try penetrene.. the liquid stuff... works well

you can try breaking the thread by giving the head of the socket head a good few hits with a hammer.

Oversize allen key is another good one suggested already... you could use an oversize allen key and also tap the key at the same time..

Ezyout's, as with many people, are not my friend, however everyone's got their own opinion.

but if you're going to the extent of drilling the head off.. then it doen't hurt to try the ezyout..


good luck.

Problem with easyouts is if they break ya cant drill them!
I sold a bike once with only 1 exhaust stud & a broken eastout in the remaines of the second :oops:

Bacca, it's hard work, but if you break an easyout, use a hardened centre punch to shatter it, and dig out the remains. Best easyouts I've found are the tapered kind, with straight flutes, not the spiral flute kind. (especially the $9.95 ones !!) sort of look like a left hand reamer. You have to get them from Sidcrome or Snap-on, and you know what that means..................$$$$$$$$$

A nice center drill shouldn't be a problem for an easyout (especially the el'cheapo ones)

as stated... personally i wouldn't used them.

just bore it out! do it... i know you want to.
