ABSTRACT:
Disclosed is a device for sorting fasteners, particularly screws, wherein defective fasteners are identified by a series of mechanical and electrical gauging stations arranged one after the other on a rectilinear conveying track and controlling ejection devices for eliminating screws which are not true in size or in quality. The mechanical gauging stations precede the electrical ones operating on the eddy current principle, in order to prevent neutralization of error signals generated by the electrical gauging stations. In this manner a very high accuracy of the entire sorting device is achieved.
