Anyone know the dimensions of the world's smallest coil spring and what it has been used for? A quick "google" did not throw up any clues.

I don't expect this is the smallest - its probably a developing requirement - but this is certainly small. I "snipped" it from a web page . http://www.d-mec.co.jp/eng/products/acculas/acculas_zoukei.html

I can't take it apart to measure it, but it makes my nano-pen go, "Click".

Aren't some molecules coiled springs? Jellyfish Nematocysts are coil springs....

Protein structures form alpha helices that could be described as a coil spring, don't know if you could really apply it in any engineering sense though.

Did we arrive at a consensus, was Tony the winner and were you cheating on something from another forum, ajb?--I don't think molecules should count...
