Hello all,
Does anyone have any information on the effect cadmium and galvanizing (hot dip) has on the torque values required to achieve the desired tension in A325 bolts?

Hot-dip galvanizing as-received is similar to bare steel - 0.20-0.40, therefore it needs a lubricant. Amount of lubricant dictates the friction reduction.
