Tapping screws belong to the thread-moulding screw family. When screwed into a pre-prepared core hole, these screws shape their own counter-thread.



Guideline values for selecting the correct core hole diameter are contained in DIN 7975.



Shape C = thread with tip


Shape F = thread without tip


Shape R = thread with rounded tip
