Chain vs. Belts?!?

A 4mm metric allen key is recommended( what it is designed for) which is handy for us being an Australian team and using a lot of metric( M5 and M6) hardware. In reality 5/32 inch is 3.97mm so there isn't exactly a big difference, probably not worth worrying about.

We often confuse 4mm and 5/32". The Dark Soul chain tool is one of the fortunate and rare cases where using metric or imperial has no noticeable effect.
0.03mm is ~0.001" so it's well within the tolerance on the hex and on allen keys.
