You now have threaded studs on the bike that you can simply slip the rack stays over, and secure the rack with wing nuts.
Also works well if you want to have full-stay fenders that are quick to mount and remove.
You could do the same with allen screws, and do away with the screw heads. Temp covets for the studs could be cap nuts, screwed on finger tight when not in use. Wing nuts are still a good choice for attachment
