Swell Neck
1.813 0.875 a The swell neck is applicable to all standard forms of large rivets except the flat countersunk and oval countersunk head types. b All dimensions are given in inches. The following formulas give basic dimensions for manufactured shapes: Swell Neck, E = D + 0.063; K = 0.500 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. Basic dimension as manufactured. For tolerances see table footnote on page 1866. American National Standard Dimensions for Hold-On (Dolly Bar) and Rivet Set Impression ANSI/ASME B18.1.2-1972 (R2016)
