Help me with my knob!

Or at least the set screw in it. 

I've bought a load of these

http://www.te.com/catalog/pn/en/4-1437624-6?RQPN=PKES120B1%2F4

for a project, and the set screw is listed as a US type - UNC-2A #6-32.

What I can't seem to find anywhere is info on how big the hex tool I need for screwing this set screw in and out is.  I'm sick of losing tiny the little allen keys I've previously used to do this job, so I want to buy a dedicated hex screwdriver.  But how big should it be?

Looking at info about unified thread standard is not getting me anywhere.  Does anyone (probably in North America) know this off the top of their head?

Cheers

Rob
