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.


583 Not to start a pi**in' contest, but the correct term is "Castellated"
nut, although commonly called castle nut. Most familiar use is in the front
suspension & steering of cars/trucks to insure nothing vibrates loose.

585 Generally called a "chain binder" or "load binder", very familiar to
anyone around the flatbed trucking business. Used to securely tie down those
steel coils, loads of pipe, lumber, logs, etc. The long handle is indeed for
extra leverage, but it's not enough when tying down a heavy load, which is
why they make cheater bars, apiece of pipe about 3' long that you put over
the handle to get the extra leverage needed.
