Well, duh! Metric and SAE front-to-back, no left-to-right! You'll find a metal divider along the length of the tool that separates the two types.
One side is imprinted V-US-AMER-NAT 4-42. The reverse is METRIC 60deg; they are separated by a divider down the middle. So, hold it facing one way, and metric gauges are on BOTH left and right. Flip it over and SAE (non-metric) are likewise on both left and right. (Didn't come with instructions that would have been helpful.)
Once I figured this out, it's easy-peasy!
[BTW, I used the term "non-metric" along with SAE. The package says SAE, while the tool is imprinted with V-US-AMER-NAT. Someone who knows more will have to explain if there's a difference between V-US-AMER-NAT and SAE, or if that's a distinction without a difference.]
The SAE (non-metric) pitches are in TPI (threads per inch), and a 1/4"-20 bolt matched perfectly to the gauge labeled 20, and 3/8"-16 matched perfectly to 16. Metric thread pitch is by the distance in mm between threads in mm. That's how the gauges are labeled.
I put it to use immediately on my telescope adapter rings to distinguish tiny metric M 1.0 from M 0.75. After struggling to eyeball thread pitches with calipers, this works like a charm. It has plenty of metric and SAE sizes but double check the range to make sure it includes yours. My packaging states:
- SAE 4-42
- Metric 0.25-5.5mm
- 60 degree thread profiles
Thumb wheels loosen or tighten the constellation of sizes so you can swing the ones you need into view and stow the others.
You could use it to measure tapped threads INSIDE a hole or bolt if the hole is large enough to insert the gauge; I measure about 6mm clearance for inserting in a hole.
Others mentioned rusting. Like a lot of machine tools, it comes with a light coating of oil but will probably rust in wet environments over time, so care for it appropriately.
Numbers are inscribed into the metal with a small (2.5mm tall), clear font; older eyes may need reading glasses or a magnifier to read them more easily, but there's no more room for anything larger. Some reviews criticize the labels as hard to read; I think it's good enough given the space constraints.
A nice addition to my toolkit for $10!
The gauge becomes more difficult to use if you are trying to check thread gauge in place and must bend and twist your body, and look in dark places. For those uses and if a standard, common thread gauge is likely, twisting on a test nut or trying out a test bolt will give a tactile confirmation once you have found the right gauge. However, gauges designed with actual bolts or nuts on some kind of string (to keep them together so they don't get lost) also have their defects since they become hard to twist in tight dark places. It seems most of these thread gauges are designed to be used best with loose nuts and bolts.
