OK, So, something about the AN470-AD4-2 Part number was totally bizarre to me... so I checked the last revision of AN470.
For 1/8 Dia rivets [#4... and for #3 and for #2 Dias also] the minimum length is [-3 = 3/16] ... so the actual MINIMUM size 1/8 Dia rivet by code-table = AN470[*]4-3
It is inconceivable to me how/why anyone would sell 'AN470[*]4-2' rivets that are completely 'off-spec'. Here is the embedded table in AN470 spec, thus...
NOTE1. AN470 rivets [Part Numbers] were actually superseded/replaced by MS20470 PN Rivets [part numbers] between 1959 and 1968
Free AN, MIL, MS. fed, etc specs are available at: https://quicksearch.dla.mil/qsSearch.aspx
In summary... an AN470AD4-2 is non-standard because it is a ridiculously short shank length... get longer rivets and use a rivet shank cutter as needed...
