Specification

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

Notice

Self-tapping screws made from stainless steels are softer than those made from case-hardening steel. These screws are therefore not able to form a counter thread in steel plates. For this reason, they should only be used in soft materials, such as aluminium.
