I went to take a photograph of something on my workbench with the aid of my mini-tripod, and something didn't feel quite right as I tightened the little wing screw that secures the head of the tripod. It turns out there was a good reason for that.
The plastic wing affair broke. Here's a view of the screw removed and on its own.
Piece of junk.
I'll have to get the remnants of the wing off the screw however I can, and see if I have a wing nut that will fit that I can glue on for a replacement wing.

Here's a method for clamping a screw thread in a vise without marring the thread.
Cut through one side of a hex nut, and use that as a primitive 'collet' to grip the thread in a vise, like so.
Now I can get pliers onto that wing remnant and crank it off the screw.

That worked fine, but my 'collet' didn't want to unscrew easily after having been clamped onto the screw in the vise. I hammered a chisel tip into its saw cut gently to persuade it to open up a bit, and it unscrewed. The chisel's tip never reached the screw's thread, so no harm was done.

I happen to have exactly one M5 wing nut in my stash of M5 stuff. Here, I've attached it to the screw using CA adhesive as a threadlocker.
Back in business.
