Default Re: What are these nut things called?

I must admit to not having tried to re-tap this type of fastener, but I have done it on a different type of threaded insert (pressnut) to allow a M3 pressnut to be used as a hand-tightenable substitute for a knurled terminal nut on a long 6BA thread. Pressnuts have a serrated ridge on the outside rim of their flange which provide serviceable finger grips. Not to be confused (although they often are by on-line sellers) with pressed nuts, which are nuts made from sheet metal stampings rather than from drilled square or hex rod.
