These are perfect clamps for just about any purpose.  I use them to secure things to my work bench prior to drilling, sawing and sanding.  Many other uses. So easy to use, and very well designed.  One of the most useful things to have around your shop. And a great price.  One thing to be careful about: make sure you are careful as you use them or you can pinch the palm of your hand pretty badly between the trigger and the grip.  I found this out the hard way!
