I have had my 110 for a couple of years now and as long as I tighten the nut well it has not slipped yet. My hub has the two cap head screws in it. Therefore you must drill out the back plate of your spinner.

I guess I am just lazy, but drilling all those holes and taking out all those bolts is a pain.
Some manufactures make there bolts so soft that by the third time you remove them you have to replace them.
I like the one nut design. Oh and always use a washer as stated previously
