Wood – How to use threaded inserts

I got these fasteners with table legs that I bought for a formica table top. I get that I need to embed the outer part with the big thread into the table, and then use an Allen key to fasten the bolts into that.

But how do I get the outer part into the wood? Do I drill a little hole and just screw it in?

If you have a micrometer, measure the outside diameter of the entry point in the barrel (illustration below)

If you don't, measure with a tape measure that will do increments of 1/32". Next, measure the depth of the barrel, and mark that depth on a drill bit that is sized to the entry point of the barrel (plus a few mm to cover the depth of the screw that goes into said barrel). Now, simply drill into the material and then screw the barrels in.
