Brad,
Those are stamped and formed contacts. There are a gazillion
types on the internet and ebay. With a quick look, I couldn't
identify a source for the type you are using.
If I were doing what you describe, I wouldn't use those contacts.
It will be difficult to keep the solder out of the top spring
contact when you are soldering them in. Instead, I would use
cylindrical machined socket pins, like this one:
https://www.mill-max.com/products/rec/0297. These types of
contacts have the spring socket contained within the body
cylinder, allowing the solder to flow around the entire contact
without having to protect the spring. They are probably more
expensive, but will result in less rework and possible board
damage.
The link I gave above is for a Mill-Max part I picked at random.
When I do this, I sometimes buy some machined contact IC sockets
or socket strips on ebay, and remove the contacts. This is a very
inexpensive way to get them. The strips/sockets are made of
thermoplastic material, and a little encouragement from the heat
gun makes them very easy to remove.
Figured if anyone might know it might be you guys.
I am making some double sided boards that will not be plate through – so I need these metal IC socket pins you install in a strip and then cut after soldering on both sides. I have a roll of about 500 but will need many more.. I just can’t find more because I don’t know what their proper name is. I’ve tried ‘IC socket strip’ but I get the strips with the plastic tops.

Many thanks if anyone knows what the proper name is and/or where to get them.
