Broken Slider Bolt

Hi,
I tried tightening the belt for the alternator and steering pump by tightening the slider bolt near the alternator and it snapped in half (I was stupid and didn't loosen the lock bolt). Is there any danger in driving with only the lock bolt in place for a few hundred miles (I'm in the middle of the boonies right now)?

Thanks!

As long as the belts are tight you should be fine.
