Have not confirmed that fact yet.
I decided to do a little test. So I decided I should pull out my most accurate digital calipers, my mitutoyo 500-196-30 / CD-6" ASX
I measured multiple metric and SAE sets.
The L wrenches I have had for some years and they are all gold-plated and they look great, at least for the sets I measured.
The newer sets have regular screwdriver handles and those are very new.
0.05" = 1.27mm measured at 1.27mm
1/16" = 1.5875mm measured at 1.57 to 1.58mm
5/64" =1.9843mm measured at 1.97mm
1.5mm measured at 1.49mm
2mm measured at 1.98mm
I didn't bother measuring anymore, it seemed pretty clear to me that they actually are different. Especially if the 5/64ths and the 2 mm are not measuring the same.
