Abstract: The invention relates to a method of evaluating the play between two threaded components, a first component comprising an internal thread, and a second component comprising an external thread that corresponds to the internal thread of the first component, the components are engaged with each other the method comprising the steps of: applying a torque from a motor to said components such that a first side of the internal thread is in contact with an opposing first side of the external thread wherein the two components are mutually rotated, which mutual rotation yields a mutual translation movement of the two threaded components; fixing the components with respect to each other, such that no mutual translation movement is allowed, whereas mutual rotation is still allowed; withholding the applied torque to one of said components, until a second side of the internal thread is in contact with an opposing second side of the external thread, monitoring the applied torque during the above steps by determining the pow
