Length tolerance of all rivets is plus or minus 0.016 inch. Approximate proportions of rivets: flat head, A = 2.00 × D, H = 0.33 D ; flat countersunk head, A = 1.850 × D, H = 0.425 × D ; button head, A = 1.750 × D, H = 0.750 × D, R = 0.885 × D ; pan head, A = 1.720 × D, H = 0.570 × D, R 1 = 0.314 × D, R 2 = 0.850 × D, R 3 = 3.430 × D . Note: ANSI Small Solid Rivets may be obtained with or without points. Point proportions are given in the diagram in Table 2a. b Given for reference purposes only. Variations in this dimension are controlled by the head and shank diameters and the included angle of the head. c Tabulated maximum values calculated on basic diameter of rivet and 92° included angle extended to a sharp edge. d Minimum of rounded or flat-edged irregularly shaped head. Rivet heads are not machined or trimmed and the circumference may be irregular and edges rounded or flat.
