An L6×4×1/2 single-angle tension member of A572 Grade 50 steel ($F_y = 50$ ksi, $F_u = 65$ ksi, $A_g = 4.75\ \text{in}^2$) is connected through its long leg by a single line of four 7/8-in.-diameter bolts in standard holes, giving a shear-lag factor $U = 0.80$. By LRFD, the design tensile rupture strength $\phi_t P_n$ of the member is most nearly:
