Mechanical PropertiesGrade 2

1. 1. The proof load in pounds for nuts is computed by multiplying the proof load stress, in psi (lbf/in2), for the nut grade, size, thread series, and type, as shown in Table 2, and tensile stress area in square inches (in2), for the applicable size and thread series shown in Table 3. (For tabulated values see Appendix A.) To convert the inch based pounds per square inch (psi) values above to metric Megapascal (MPa) units, multiply the above values by .00689.
