● A sheet metal repair has been made using two pieces of aluminum
riveted together. Both pieces were 0.032 in. thick. What rivet should
have been used? Answer: MS20455DD 5-5
Answer B is correct.
Using Exhibit 1 and Exhibit 7 from the computer Testing Supplement
for Inspection Authorization, it can be determined that rivet length is
measured in 16ths of an inch and that the correct length should be 1.5D
beyond the material thickness. In this example, the rivet diameter is not
given and must be determined by the part number of the rivet. From
Exhibit 1, we can determine that the rivet diameter is expressed in 32nds
of an inch. A "D4" or an "AD4" rivet is 4/32, or 0.125 in. in diameter,
and a "DD5" rivet is 5/32, or 0.156 in. in diameter. The minimum length
for the "D4" or "AD4" rivets is 1.5D + MT = 1.5(0.125) + 0.064 =
0.2515 in. The minimum length for the "DD5" rivet is 1.5D + MT =
1.5(0.156) + 0.064 = 0.298 in. The length of the "D4-3" rivet given as
answer A is 3/16 = 0.1875 in, which is too short. The length of the
"AD4-4" rivet given as answer B is 4/16 = 0.25 in, which is too short.
The length of the "DD5-5" rivet given as answer C is 5/16 = 0.3125 in,
which is acceptable
