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

Cotter Pins
by Steve from Algonquin, Illinois on June 15, 2014
I ordered cotter pins with my new prop and hub kit and when I unpacked my package, I totally forgot about the cotter pins and recycled the box, cotter pins and paper insulation in all. In the future, I would suggest that you tape smaller parts to larger boxes so dummies like me won't toss them out.

Not the right kit!
by Anthony from Wyoming, Michigan on May 12, 2015
The propeller nut kit that came with my prop was the wrong one. I was lucky enough to be able to use the old parts to put the prop on. Unfortunately I had to pay freight to return the item back to Iboats.com They made the mistake and they should of paid the freight by sending me prepaid return labels. They did not. Not sure I would buy from them again.
