so i was browsing harborfreight the other day and came across these:

and i cannot figure out how they work! i was considering just buying them to figure it out, but i typically use a torque wrench on anything that needs even a semi precise torque.
i was just wondering if anyone knows how these work? i cant see any they slip, click, twist, etc. anyone have any experienc with them? i dont think i will buy them, just curious how they work.
