    Tolerance is the magnitude of permissible variation of dimensions from the specified value.
    Limit dimensions given below and above the nominal size are called as bilateral tolerances. Limit dimensions given above or below the nominal size are called as unilateral tolerances. In unilateral tolerance, variation is permitted only in one specified direction and in bilateral tolerance variation is permitted in both directions.

    Slip gauges have bilateral tolerance and they tend to cancel errors as they have tolerance on individual blocks.
