When computing the ultimate strength of rivets in shear, the following values in pounds per square inch of the cross-sectional area of the rivet shank shall be used: PSIG Iron rivets in single shear 38,000 Iron rivets in double shear 76,000 Steel rivets in single shear 44,000 Steel rivets in double shear 88,000 When the diameter of the rivet holes in the longitudinal joints of a boiler is not known, the diameter and cross-sectional area of rivets, after driving, may be selected from Table 1, or may be ascertained by cutting out one rivet in the body of the joint. TABLE 1 - SIZES OF RIVETS BASED ON PLATE THICKNESS Thickness of plate – inches 1/4 9/32 5/16 11/32 3/8 13/32 Diameter of rivet after driving – inches 11/16 11/16 3/4 3/4 13/16 13/16 Thickness of plate – inches 7/16 15/32 1/2 9/16 5/8 Diameter of rivet after driving – inches 15/16 15/16 15/160 1-1/16 1-1/16
