I believe it is a #10 but would have to check. In the starter kit that comes with the machine is a set of allen wrenches and also 2 other L shaped allen wrenches with a much shorter length on the short end of the L. One of the uses for one of these allen wrenches, was to be able to tighten up the allen head screws on the cap driver attachment bar. You will notice that the large round headed thumbscrews cannot fall out because the space between the round bar and the upper bracket is too close to allow it. Hence, the short head L allen wrench, to be able to get it beween the bar and the upper bracket to tighten the allen head screws that are used for this purpose now......guess a guy/gal could revert back to the "old" way of doing this...I agree the screws that come with the cap driver now do not seem to be the best thing that Melco has ever invented. I like the idea but not the material that they are made out of.
