grumpy,

Usually the bolts being metal oxidise to the alloy which is like welding two pieces of metal together. I have in the past had to drill out and tap a new thread because the bolts snap off when trying to undo them.

Note that it does not happen often but when the bolts have not been undone for a very long time this does happen.
