EJOT Spiralform® The thread formers for metals Compared to thread-cutting the thread-forming method is a technically and economically better solution since thread-forming and installation are done in one single step, resulting in an accurate, tight-fitting female thread. Characteristics: - the formed thread corresponds to the metric ISO-standard thread DIN 13 - the circular section provides complete overlapping of the flanks which causes a higher strength durability - easier application with the Spiralform Plus point - wide range of materials Advantages of the EJOT Spiralform® screw - the process of thread cutting with all additional costs like cleaning and inspection can be omitted - less rejects and scrap
