I have been using the expensive thumb clamps for a few years to hold planking but recently stumbled onto wire clamps(tie downs) when working on a project for a friend. If you use a small screw and he wire clamp turned over or not they work great! Very cheap at hardware stores. I got a box of 100 plus screws all for less than $5. No more nail holes in planking or spring clamps that creep or dont hold. Hope this helps others!
