a Tolerance for diameter of body is plus and minus from nominal and for 1 ⁄ 8 to 1-in., incl., equals +0.030, − .025; for sizes 1 1 ⁄ 1 ⁄ 2 -in. equals +0.040, − 0.030; for sizes 1 5 ⁄ − 0.022; for sizes 5 ⁄ − 0.027; for sizes 1 3 ⁄ 8 and 1 8 and 1 8 and 1 − 0.037. b Note 1. Basic dimensions of head as manufactured. All dimensions are given in inches. The following formulas give the basic dimensions for manufactured shapes: Button Head, A = 1.750 D ; H = 0.750 D ; G = 0.885 D . High Button Head, A = 1.500 D + 0.031; H = 0.750 D + 0.125; F = 0.750 D + 0.281; G = 0.750 D − 0.281. Cone Head, A = 1.750 D ; B = 0.938 D ; H = 0.875 D . Pan Head, A = 1.600 D ; B = 1.000 D ; H = 0.700 D . Length L is measured parallel to the rivet axis, from the extreme end to the bearing surface plane for flat bearing surface head type rivets, or to the intersection of the head top surface with the head diameter for countersunk head-type rivets. c Note 2. Dimensions of manufactured head after driving and also of driven head. d Note 3. Slight flat permissible within the specified head-height tolerance. 2 -in. size equals +0.020, 1 ⁄ 4 -in. equals +0.035; 3 ⁄ 4 -in. equals +0.040,
