Do yourself a favor, and try an loosen those 5mm hex drive bolts first. As with many of mine, they were over torqued to the point of total amazement. I think they withdraw the impact driver while it's still on, as the upper part of the hex if often torqued so it doesn't index with the bottom part. You can tap a new 5mm hex bit in, then use a hammer type impact driver to break it loose if "normal" Herculean methods don't work. Just make sure to keep the bit seated all the way!
One of mine stripped and since it's in a recess, had to use a rotary tool with carbide bit to cut a slot in it, (no room for a small, Dremel type, abrasive wheel to slot it). Finally got it, though I was bordering on the "weld a nut to the dang thing" method. This was on a new machine, corrosion was not a factor.
