For 100mil spacing headers look at the AMPMODU series. Download
the complete datasheet and you will find the various terminal options
and tools. The AMP datasheets and drawings are excellent.

In the AMP documentation some of the terminals are
called "Crimp and Poke" others are called "Crimp Snap-in".
I refer to all of these terminals that  you crimp and then poke
into the receptacle as crimp-n-poke.

I have a tool from AMP labeled "Service Tool I" that looks like it could crimp
these terminals. It is a low-cost tool that is similar to the "Amp Champ".
I have never used it for crimping since I have the crimp tool.
