Tiny Tuesday - Miniature Bolts

I am inveterate squirrel, so when something breaks down irreparably, I will inevitably strip it down to see if there is anything worth keeping. My iPod suffered this fate two or three years ago and I was fascinated today to find the small plastic bag in which I had kept all the tiny nuts and bolts. None of the bolts is much bigger than 2-3 mm in length. As I have not yet found a use for them, I thought I would photograph them under the digital microscope so at least they can contribute to my blip journal.

Please note for any competition judges I have , of course, ensured  that there are an odd number of bolts.
