Standard Woodruff Keys

Stanho standard woodruff keys are machined metal fasteners used to transfer torque from a shaft to gears and function as a fail-safe device ensuring that the key breaks before the gear does; thus reducing replacement costs. Standard refers to the keys having ANSI Standard dimensions including length, height, radius and distance. The other type of keys would be metric.

Below are technical reference charts for our standard keys.

All dimensions are given in inches.
The key numbers indicate nominal key dimensions.
The last two digits give the nominal diameter B in eighths of an inch and the digits preceding the last two give the nominal width W in thirty-seconds of an inch.

The key numbers with the -1 designation, while representing the nominal key size have
a shorter lenth F and due to a greater distance below the center E are less in height than the
keys of the same number without the -1 designation.
