I can't seem to find any info on what size hex I need for a Japan Strat bridge. It's smaller than anything metric I have; Sears only has really small hex wrenches in English.

I bought a set of two wrenches that includes .050 and 1/16; the .050 one fits my U.S. guitars. The Japanese bridge is between the two. I assume .050 means 5/100 or 1/20 of an inch. I guess that below a certain size they cut inches into hundredths.

Thanks!
