Among cruising sailors, there is an old adage:

"There are no hardware stores at sea."

IOW, if you have a device on board, you also have a full set of
spares
for the device.

Same applies to your abode.

Saves lots of extra trips to the hardware store.

It's kind of funny, because I sorta live by that very adage. There
are lots of things in my home that are spared. Including plumbing
stuff. Just never seems to fail that that one piece...

There are times when a spare is a fully assembled and tested
replacement device in addition to the individual replacement parts.

An example on a boat is a head pump.

Repairing a head on a boat makes changing out a toilet on land feel
like a form of fun entertainment.
