keyways
Channels for keys
Keyways is the plural of keyway, a slot or groove cut into a shaft or hub to receive a key—a small piece of metal that locks rotating parts together and prevents slippage.
In machinery, keyways ensure that gears, pulleys, and wheels turn with their shafts rather than spinning freely: The machinist cut keyways into both the shaft and the coupling.
