BS 4235-2:1977

This standard BS 4235-2:1977 Specification for metric keys and keyways is classified in these ICS categories:

• 21.120.30 Keys and keyways, splines

This International Standard specifies the dimensional characteristics of Woodruff keys and of the alternative Whitney key and of the corresponding keyways in shaft and hub. It also gives the relationship to be observed between the diameter of the shaft and the section of the key for both torque transmission and positional applications.

Dimensions, relationship with shaft diameter for torque transmission and positional applications. Minimum tensile strength of key material.
