allen head size

[LowClassCC]

ok... the black idle gears in the associated 6 gear transmission use 4 micro screws per gear to hold the bearings. what size allen wrench do these screws take? none of the allen heads in my entire collection and anywhere near small enough so i need to go shopping. i just want to make sure that if i find a set it has the right size in it.

dont know if this will help. the smallest i have is 1/16 allen. i just took apart my six gear and that allen was just too big. ae has an allen wrench kit no 6950. the sizes are:
.050" Allen Wrench
1/16" Allen Wrench
5/64" Allen Wrench
3/32" Allen Wrench

maybe the .050?

nahh i have that size.. the 2 smallest sizes i have not tried yet since i cant find them locally are 0.7mm and 0.9mm. i found them online but im still hoping i might find them local first. if not i will just order a set that goes down that small.

it's a .035 or something like that.

mcmaster lists 2 sizes smaller than .050".

.035"
.028"

got to be one of those 2......

i'm 99.9% sure it's the .035.
