We called them transfer points.These are Nielsen Transfer Screws, they are the same principle as a transfer punch except they can be threaded into a piece so you can put metal or wood against it to mark a bolt pattern. This 3 size set was about $36 shipped.
I’ll be using these on an inboard shock crossmember bracket to transfer the bolt pattern to the inside of my frame.

When I worked on A-6's, we had the high dollar deluxe gun. It was a blast.Bought this air over hydraulic nutzert/rivnut, or whatever they are called today, insert tool.
Put in over 100 hundred insert with it. No issues. View attachment 413521
Not today. Make sure to hold it straight in your hand and low enough on the handle.
See that big black knob on the back. It moves back when the trigger is pulled. Then spring loaded center moves forward. It bit me.
