Um, it's a nut and does what it's supposed to do. Pretty pricey for what it is though.

Looks OK by William - Cadillac, MichiganAugust 21, 2012
Ordered this along with the prop I bought. Thought I needed it, but it's not used with the prop. The prop ordering page was a bit confusing, but I have a spare now for my aluminum prop I guess.
