1 3 ∕ 4 1 47 ∕ 64 a All dimensions that are tabulated are given in inches. This standard does not apply to Boiler Rivets b Tolerances of the rivet diameter are as follows: at position X , plus 1 ⁄ 32 inch, minus zero; at position Y , plus zero, minus 1 ⁄ 64 inch; at position Z , minus 1 ⁄ 64 inch but in no case shall the difference between the diameters at positions X and Y exceed 1 ⁄ 32 inch, nor shall the diameter of the shank between positions X and Y be less than the minimum diameter specified at position Y . c The location of positions Y and Z are as follows: Position Y is located 1 ⁄ 2 D from the end of the rivet for rivet lengths 5 diameters long and under. For longer rivets, position Y is located 4 1 ⁄ 2 D from the head of the rivet. Position Z (found only on rivets longer than 5 D ) is located 1 ⁄ 2 D from the end of the rivet. d At the recommendation of the British Standards Institution, these sizes are to be dispensed with wherever possible. 1 3 ∕ 4 1 3 ∕ 4
