6.7 Chuck accuracy
Describes 90 degree and 60 degree serrations and jaw nuts applicable to 90 degree and 60 degree serrations for mounting the top jaws on the base jaws of power chucks, in order to ensure interchangeability. Also specifies the geometric tests for self-centring, power-operated chucks with two or more two-piece jaws (serrated type), and the corresponding tolerances which apply.
