Cover Pins (pins solely holding covers on): set length pins that are domed externally and easily spread internally. These may appear to be flush on some smooth slabs as they are buffed to the ends with the rest of the stock. But start out same. For slabs that can be made mostly uniform by GEC (jigged bone), they will appear domed and sitting a bit proud of slab because the slab can be made to fit exact thickness front to back. For variable height slabs (stag, primitive, etc) the slabs will be drilled and countersunk to certain depth from liner; so if stag is thicker in one spot, pin will be sunk deeper.
Nails (pin stock thru frame): these are from lengths of pin stock. They will be domed on uneven surfaces or buffed flush on smooth surfaces.
There may be cases where these expectations are not correct; but I can't think of an example.
Obviously GEC could use lengths of pin stock everywhere; they don't because it is more time efficient, has less failure over time, and causes fewer initial pin cracks to use set length pre-domed pins for slabs.
