I'm sure some old timers here will remember back in the Heathkit days, every kit included a round red plastic thingy that held 4-40 nuts in one end and 6-32/8-32 nuts in the other. I remember I had at least a half dozen of the darn things in my toolbox. I took them for granted I suppose because I don't have a single one left and there are many many times recently when I have regretted not keeping a few. They were absolutely handy when you had to get a nut started inside a chassis while holding the screw with the screwdriver blade in the other hand. They were slightly flexible and you could start a nut on a screw in the tightest of spaces.
