I was going through a spare parts bin that was with the boat and came across a couple of things I couldn't identify. Can anybody help out with positive IDs or a use guess?
First is a set of three-piece white clips. The two cylindrical pieces would have a screw put through them, allowing the piece with the arm to rotate freely, and the cap would cover the screw head (picture shows the three pieces exploded). There are six of these sets.

Second is a two-piece stainless steel fitting. Each piece has a threaded hole that accepts this large (5/8" ?) bolt. The piece with the hooks looks like it could be twisted/hooked onto a cable or something.

Any ideas, esteemed sailors?
