Anyone have some suggestions how to easily remove these? Two stainless steel M5 bolts decided to break on me. Should I try using a cobalt drill bit to clear the holes?

Good penetrating oil (Aerokroil), left handed drill bit, screw extractor.

there isn't anything sticking out on either side that you can grab with pliers? if not the above the drill alone may pull the screws out.

OH how did they break?

Once you get them out, be sure to use anti-sieze on the threads to help keep this from happening again. You can try an old trick I did one time, was to take a electric soldering iron and touch it just to the screw and hold it on until the screw gets warm. However, this might not work so well on an aluminum frame. Aluminum wicks off heat like crazy.

I wound up slotting the remainder of the screws with a hacksaw and carefully unscrewed them with a flat screwdriver.
