I have been using a similar method for years now, that I prefer. I use
a pin vise to hand drill holes in nylon 4-40 screws and then screw these
into the leadout holes. I tap the holes in the tap with a 4-40 tap, and
then soak them in CyA glue and retap them. This system works great,
and there is less chance of a nylon screw coming loose.
