    GD&T -any draft angle specify method?

    i have a plastic part, which have a screw hole for tapping screw, i am wondering why no draft angle specify in drawing? is it good to specify the draft angle as consder the pin to form the hole can be broken. and the draft affect screw tigthen torque. How to specify the draft angle in GD&T format?
