Thumb Screws are great
These are good quality, well machined, and larger knurled surface area makes using them easy.

Appear to be of good quality
I have not used these yet. As long as they don't break while tightening them (may have to you a set of pliers to tighten sufficiently to hold pieces of rebar in inserts. We'll see.

Cheap, poorly manufactured, ruined a $200 lighting rig
I screwed one of these screws in to tightness, by which I mean, not loose at finger strength with no tools involved. I tried to unscrew it, and it ruined my lighting rig, because I had to use the wrench pictured in this photo to take it out, which stripped the threads of the lighting rig.DO NOT BUY THESE CHEAP PIECES OF JUNK.
