I think my Metric set is from 4mm to 21mm.

WOW that is a huge set, 4-21 no skips.
Wish my set was that complete.![]()
These are all metric, will a snap-on dealer have a way to look up all the wrenches made in that series. Most sets I have seen do not included every step by 1mm from 8 to 22.
1/4,5/16,11/32,3/8,7/16,1/2,9/16,5/8,11/16,3/4,13/16,7/8,15/16,1"
just for reference.
metrics i'm sure you can figure out.

3/16" - 1"
Really... because when I multiply 3 x 2 I get 6, and when I multiply 16 x 2 I get 32... so 3/16 would be 6/32.Bob,
3/16 is 9/32, they are one and the same.

Thank God, I've been dragging this pig around for 25 years and never used it, at least now I know what it fits....Hardest wrench to find in sae is 1 3/16 commonly used on older transfer cases in 4x4 trucks for the fill and drain plugs.
