Metric Machine Keys (DINS / ISO)

Metric machine keys, also referred to as DIN or ISO keys, are machine keys that have metric dimension rather than imperial or English measurements so you will see millimeters instead of inches or fractions.

Metric machine keys function in the same way that other keys do. They connect a rotating machine element to a drive shaft so that torque can be transmitted.
