Explanation:

  • In different connections, the bolts are subjected to a combination of shear and axial tension. In a tension or hanger connection, the applied load produces tension in the bolts and the bolts are designed as tension members.
  • But bolts are most suitable to carry axial tension, as they can fail in shear prior to tension failure.
  • Bolts are always subjected to tensile stress when nut is tightened. The washer will be in compression.
