AN435 canceled 3 March 1969: "USE MS20613 AND MS20615" (AN435 Rev 7). Pick by material: MS20613 covers carbon steel and CRES; MS20615 brass, copper and nickel-copper (Monel) (AC 43.13-1B Table 4-8; MS20615G title). AN435 is a round head rivet and both MS sheets are universal head (AN435 and MS20613F / MS20615G titles), so the head is not the same shape. Both MS sheets are marked superseded by NASM20613 / NASM20615.
