Great clamps! I bought two of these to hold a desktop power tool (mini) because I can't permanently attach it to a table. I also use this to hold the pieces of wood to the table while I cut the piece out of the wood. For the desktop mini tool, I first laid down two layers of non-slip carpet material to keep the tool in place. This way the clamps hold tight and the bench tool doesn't move while cutting. The clamps are strong and hold without slipping. I am very happy with them as a multipurpose clamp. What more could you ask for than the clamps holding up well and the screw turning easily?
