> Better to make sure you have end caps on the screws as you won't really use them much, if at all in the alps, but they will be in and out of your bag etc.. so make sure you protect the rest of your kit and bag. Or have something to wrap them in when you put them away, old crampon bags are good.
This is a good point. If you want a cheap and cheerful protector for 3 or 4 ice screws whilst they're in your pack, cut the bottom 6" off a 1 litre plastic milk container.
