I don't actually attach the 2x2 squares to my clamps. My big Bessey clamps don't usually need them; I use them mostly on smaller clamps and c-clamps. If I really need a third hand, I'll use a piece of double-sided tape. I really like Dave Paine's idea of drilling a small counter-bore and using a small rare-earth magnet. I might do that next time I'm in the shop. It's minus 22 here in Iowa this morning and my shop will be much too cold to do anything today.
