Self Tapping Thread Insert Technical Parameters

- Jun 17, 2019-

Fastening technology from FYS is in successful application in a wide variety of different industrial sectors around the world. FYS technology provide a self-tapping threaded insert with external and internal thread, cutting slots or cutting bores. A continuous process of further development has brought about a number of major improvements to product characteristics.

Self tapping insert 302(with cutting slot) is recommended for most application cases. In certain materials, this insert demonstrates a minimal inward springing action, so creating a certain screw locking effect.If this effect is not required, we recommend using Self tapping insert 307/308.

Self tapping insert 307/308(with cutting bores) was developed for materials with difficult cutting properties. This insert has a thick wall and the cutting force is distributed over three cutting edges.
