Plugs and Holder

[Bill Tattersall]

I found these in a box of old tools. The plugs have a hex head on them and are stored in the holder. They can be installed using a matching hex socket in the holder. Any idea what they're purpose is.

They are known as transfer punches or transfer screws.

They screw into threaded holes in a part and accurately transfer the hole centers into a new piece.
