Just posted this week's set:

583: Castle nut - the bolt has a hole for a cotter pin, which goes through
the appropriate slot, and holds the nut in place.

585: a "Come-along" - the two hooks hook to chains that need to have
tension applied - the long handle gives you leverage, and the interesting
clevis arrangement toggles and holds it in the retracted position.

586: looks like the end view of a small squirrel-cage blower.

Cheers!
