For a rotating object, if the right-hand fingers follow the curve of a point on the object, then the thumb points along the axis of rotation in the direction of the angular velocity vector. A torque, the force that causes it, and the position of the point of application of the force.

Maxwells right hand thumb rule: According to this rule, imagine that you are grasping the current- carrying wire in your right hand so that your thumb points in the direction of the current, the the direction in which your fingers encircle the wire will give the direction of the magnetic field lines around the wire.
