New invention. TO-220's are a hard transistor to mount on a heat sink with a lot lot tiny parts.
I got tired of fooling with them and had several hundred of these made
on an NC lathe.

It is a 4-40 nylon nut basically.

I'll sell them to anybody that wants one. $5 for one, US mailing included.
If you want more than one let me know and I will give you a price.
Comes complete with a Kapton insulator but not the 4-40 screw.

The new Maximite EFI computer will use four.
