1/4 - 20 aluminum carriage bolts. The ones listed in the link are square shank but since they are aluminum it's a simple matter of grinding down the squared edges to make them round eliminating the need to drill out the holes in the case. I recommend placing two nuts on the end of the bolt and putting that in a drill chuck. Spin the bolt and clamp a file in a vice. The drill will rotate the bolt in the same Isis while you file down the corners. Once it is rounded you can finish off the shoulder very nicely.
