Example	MS20470AD4-5 — 2117-T4 aluminum alloy, 1/8 in diameter, 5/16 in long

Dimensions are in inches. Tolerances unless otherwise specified: decimals ± .010.
For part numbers of rivet length not listed, show the 1/16 increment required.
Additional 1/32 length increments are obtained by adding -5 after the last digit or letter of the part number: MS20470AD4-12A-5 is 2117-T4, 1/8 diameter, 3/4 + 1/32 long, anodize clear.
Diameter is in 1/32 in and length in 1/16 in. In the alloy column, All means A, AD, B, D, DD, E, K, T and J are all tabulated for that dash; otherwise only the listed codes are.
Ring on 7050 rivets: outer diameter at most 75% of shank diameter, depth at most .010. Required on 7050 rivets manufactured after 2 July 1990.
Manufacturer's identification is required to be depressed on rivet heads with a shank diameter of .125 and larger manufactured after 2 July 1990.
Aluminum alloy 2017-T4 rivets with 33 ksi minimum undriven shear strength were acceptable until 2 July 1990.
Rivets may be furnished with plain ends, or with chamfered or radiused ends to the S and T dimensions.
Interchangeability with AN470: MS20470 rivets of like dash numbers are universally, functionally and dimensionally interchangeable.
