What it is for
LAS lists it for the case where a hole has been opened up to the next size but the new rivet has to match the heads around it. Whether an oversize repair is acceptable at all is a question for the SRM, not the parts catalog.
Compare the standard head: MS20426. Hole sizes: drill chart.
