I don't think that ^ will work, it looks like the hub axle sits entirely within the dropouts and male bolts then thread in from the outside. It might be possible to file down the bolt threads just for the section that'll sit in the dropouts once installed. Not ideal though.
You’re saying that filing a bit of material of the not-threaded portion of the bolts won’t work? And that is better to file a bit off the threaded section? I guess it would be best to file down the thread section closest to the smooth section?
