About Parallel Key

Keys transmit torque between a shaft and a hub through matching keyways — the cheapest and most common shaft-hub connection.

Standards DIN 6885 · JIS B 1301 · ISO 773

S45C medium carbon steel: The standard, strong and inexpensive.
304 stainless: Food machinery and wet environments.
316 stainless: Chemical and marine service.

How to choose

Size is width x height x length; width and height follow shaft diameter.
Buy long and cut to length rather than short.
For reversing drives consider two keys or a locking assembly.
