3.938 a All dimensions are given in inches. Basic dimension as manufactured. For tolerances see table footnote on page 1866 . The following formulas give basic dimensions for manufactured shapes: Flat Countersunk Head, A = 1.810 D ; H = 1.192(Max A − D )/2; included angle Q of head = 78 degrees. Oval Countersunk Head, A = 1.810 D ; H = 1.192(Max A − D )/2; included angle of head = 78 degrees. Length L is measured parallel to the rivet axis, from the extreme end to the intersection of the head top surface with the head diameter for countersunk head-type rivets. b Sharp edged head. c Rounded or flat edged irregularly shaped head (heads are not machined or trimmed). ANSI/ASME B18.1.3M-1983 (R2016), Metric Small Solid Rivets, provides data for small, solid rivets with flat, round, and flat countersunk heads in metric dimensions. The main series of rivets has body diameters, in millimeters, of 1.6, 2, 2.5, 3, 4, 5, 6, 8, 10, and 12. A secondary series (nonpreferred) consists of sizes, 1, 1.2, 1.4, 3.5, 7, 9, and 11 millimeters. British Standard Rivets British Standard Rivets for General Engineering.— Dimensions in metric units of rivets for general engineering purposes are given in this British Standard, BS 4620;1970, which is based on ISO Recommendation ISO/R 1051. The snap head rivet dimensions of 14 mil - limeters and above are taken from the German Standard DIN 124, Round Head Rivets for Steel Structures. The shapes of heads have been restricted to those in common use in the United Kingdom. Table 3b shows the rivet dimensions. Table 3a shows a tentative range of preferred nominal lengths as given in an appendix to the Standard. It is stated that these lengths will be reviewed in the light of usage. The rivets are made by cold or hot forging methods from mild steel, copper, brass, pure aluminum, aluminum alloys, or other suit able metal. It is stated that the radius under the head of a rivet shall run smoothly into the face of the head and shank without step or discontinuity.
