Not sure what size head you need, but can you mold in a rubber bumper with
threaded stud on the backside? Something like

other products and maybe something will click.

Ah, and the ones that come with many toggle clamps are even closer to
size and shape I'm looking for. Rubber however would not last long and
if Teflon or some other high temp plastic was used it would leave a hole
all the way through the part. Teflon is often used as an insulator to
keep an area that will be cut away from forming. On a large part it can
save several pounds off the shot weight. Save big buck$ over time...
