Set screw size help fast!!!

[tapeworm]

I just snapped my Coupler and luckily had a spare (Octura Coupler Flex Hex 5mm to .150 Cable) part number OCFHE5MM15. Apparently I have every allen wrench size known to man except this one. Anyone know it off the top of their head so i don't have to buy an entire set? Thank you in advance.

Its a 6-32 set screw that needs a 1/16th" allen. At least thats what either of my octura examples use.

sv coupler takes a 1.5mm wrench(I think), I believe the octura takes an 1/16" wrench.

That makes sense since my 1.5 is a tad too small. Thank you guys.
