The hole diameters for the Demco Channel Tongue Trailer Coupler item # 12564 are 1/2 inch. It is recommended to use grade 8 hardware to attach the coupler to your trailer frame. You can find these bolts at a local hardware store as they do not come supplied with the kit because of varying sizes of trailer frames.
