Is it flush with the plate or on the block? If it is the plate just remove the plate and try to grab the little bit that will be sticking out with some pliers or vice grips. If it is flush with the block then I think your next best friend is going to be an easy-out. Plus sometimes when using the reverse direction drill bit it will spin it out as well. Good luck, I know how frustrating those little problems become when all you want to do is finish.

I have the Sears craftsman set and it's done me well. The width of the plate should have left enough for you to get some vice grips on it. There is no torque on it so it should be able to be turned out easily.

Were you using a torque wrench? They only get 106 lb. in.

That bolt should not be snapping off.

No further suggestions over what 94blackz14.2 said.

I am sure you noticed it is lb. in. and not lb. ft.

There is no accounting for bad luck, though.

1 lb. ft. = 12 lb. in.

106 lb. in. is less than 9 lb. ft.

If you were using 106 lb. ft. no wonder it broke. That's more than you tighten a lug nut. 9 lb. ft. is just snug.

For the lighter torque stuff, you usually use a torque wrench calibrated in lb. in.

Good thing you now know, so that when you put a new bolt in there, you don't break it off, too.
