Rivets Oversize
(OP)
I am looking for information about rivets oversize. Does MS20479 rivet come in 1st and 2nd oversize?
Where can I find information about which rivets have oversize?
Thanks for help.

RE: Rivets Oversize
They are by nature (or to be honest a pneumatic hammer and buck) expanded into a hole and will fill it.
So if you carefully remove a rivet then you can in most instances put the same size rivet back in. if the person taking it out has butchered the hole then you could go up a size if the structure is capable of the change.
RE: Rivets Oversize
but like 40818, i haven't heard of oversize rivets (like there are oversize hi-loks) ... as ana MRB with a slightly oversized hole, i'd suggest a slightly longer AD-type rivet that would (i expect) fill the hole.
RE: Rivets Oversize
NAS1241 and NAS1242 are oversize rivets that are commercially available,....sometimes using the next nominal diameter is acceptable (material thickness and edge distance is acceptable)

Countersunk head rivet:
NAS 1097 (BACR15CE for the Boeing folks) the oversize can be a NAS 1241 (BACR15DS). Pay attention to size and material.
Protruding head rivet:
MS20470 (BACR15BB for the Boeing folks) the oversize can be a NAS 1242 (BACR15BB or BACR15ET). Again, pay attention to size and material.
Availability and cost are a whole other matter.
