I went to take a shower and the cold water faucet handle broke loose. The grooves got stripped. Fortunately the local Lowe's hadn't closed for the evening yet, and I replaced it.
But this got me to thinking: Which parts should a homeowner keep on hand just in case something goes wrong late Sunday night when the hardware stores are closed?
Faucet valves and handles to fix any of the faucets. I've learned that one the hard way.
What else? What other common emergencies require having replacement parts on hand in advance?
