Zusammenfassung:	A method for the inspection of screws with an eddy current test probe including an insulating material body having a linear contact surface and at least one coil disposed in the body, includes orienting the coil transverse to threads of a reactor pressure vessel setscrew to be inspected, feeding high-frequency alternative current through the at least one coil, generating a coil field covering at least two threads, and guiding the linear contact surface along the threads, and a device for carrying out the method.
