Double Washers on A490
Double Washers on A490
(OP)
Just looking for clarification.Am I correct that a flat washer is required on both the head and nut side of a A490 bolt when attaching A36 steel, however a washer is only required on the nut side when attaching A992 steel.Where can I find this info?
