Specifications

DIN 7982 A4 stainless steel, type C, with tip
  • 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

Stainless steel tapping screws are weaker than case-hardening steel tapping screws. This means that these screws cannot form a counter thread in sheet steel. For this reason, they are used in soft materials such as aluminium only.
