You need a tool that looks like a screwdriver but with a slot in the end, to turn the little springs and "screw" them into the holes. Also you need drill bits and tap wrenches (though in some cases you can get by without). The springs themselves are decent quality, just make sure you get the tools.

Just what I needed to repair threads on my projects. And yes I love projecting on government projects. 1 day I might decided to patent some of my inventions.

This must have been a returned item. I received it broken, taped shut and missing pieces.
