I just discovered vented screws. They are normal socket cap screws with holes predrilled. M8's happen to have 2mm holes. I think I might get some and try to convert my hub back to 608s. They are a little pricey. The 6702 are probably cheaper but this will give you a more solid hub axle. It will be a fun experiment either way.

Good idea, but the longest vented SHCS is only 40 mm, is that enough?
