Product review (4 stars): Bolt is great, washer is a little on the small side.
I've had this installed for a couple of weeks.  The bolt worked fantastic but I found the included washer to be a bit small for my application (which is weird as this is the correct bolt).  Fortunately the washer on the original bolt was in great shape, which surprised me as the bolt was kinda icky, so I just used it.
