They act like a "second hand" to hold small pieces in-place while the glue dries. I use them as a "straight-edge" or as a weight. Butt them against two pieces to hold them together. For a modeler like myself I wish I had bought these sooner!
Like others have mentioned, you cannot pass a 3/8" bolt through the "thru holes" which is a bit of a pain. I plan on putting a 3/8" carbide drill through the thru holes to open them up properly. Most likely if you bought these for machining purposes, you can easily make this modification yourself. Just remember, they're hardened, so you need a cutting tool that is harder and to go light and slow with the cutting if you don't have a rigid machining setup. The thru holes are all chowdery and off kilter.
At this price, I think they are a great value and an asset to the shop for setup and clamping.

especially on something which is really basic, like this tool.
but, since the price was low and it has zero problems, it's well made, well shipped...
it feels wrong to say you can get better, especially for the price.
I'm sure there are blocks with more features, but these are true, they're steel, they're exactly what you would need these to be for their intended purpose. so.. you it'd be difficult to be more purpose built than these.
Want to see if your cheap calipers are reading right? Grab one of these and measure it. At 0.0002" accuracy, they're far more accurate than any inexpensive measuring tool.
These are cheap and they work. Keep them corrosion free, don't drop them and they'll last forever.
