Forgive me, I needed a pun for the day....
Be careful with High Speed Steel:
Nevertheless, the danger is real. Collisions in earth orbit occur at velocities of up to 15 kilometers per second, so a discarded bolt or lens cap could destroy a satellite or endanger astronauts. Objects as small as one centimeter across--hundreds of thousands of which lie in near-earth orbit-- could knock out critical components on a spacecraft. And such tiny items cannot be tracked by current technology, so they strike without warning.
