Its a good product. I used it to clamp corners for a pine box 2'x4' with 3/4" thickness. However - and this is important - these clamps are not designed for that kind of weight. They are designed for picture frames or any box that is lightweight.

Are these capable of clamping two different thickness pieces together in the same corner? Like a 3/4" thick drawer front and 1/2" drawer sides?

I wouldn't try it. The right angles are fixed so it can't adjust to different thicknesses. They are only good for picture frames.

will these clamps work on 1x4

They will work on the 1 inch side but not the 4 inch side.

Could shims be used to decrease min. thickness to 3/32" (or less) to glue chipboard boxes together accurately?

If I understand your question correctly, the range is from 7/16 to 3/4 inch thickness. So to answer your question, the answer is no

Works well!!

Worked well! So glad I got these clamps. Used on board thickness of 19/32” without issues. Firmly held boards in place. There is a learning curve to placing then. Held up despite being dropped. These will be my go-to clamps for similar projects in the future.

Good little clamps

These have been a surprisingly good buy. The design makes them easy to use. The spring is sturdy and the clamp keeps my small projects at a pretty good 90.
