I know what they are. They're steel thingies in a plastic base.
Well yes but, lets get a lot more specific here. Like the correct name or use for this item.
Could you please give a hint as to the size of the base.
Congratulations @nikonNUTI use a slightly more robust version at work for punching holes in Neo-fab piston cups... It's a punch set.
It is a DIE. Used for cutting threads into bar stock (making bolts).
