Thread-forming screws form threads in cast blind holes, through holes, drilled, lasered and punched holes in sheet metal parts. A thread-forming screw does not affect the structure of the material being fastened when it is screwed into it, unlike a self-tapping screw. The material moves out of the way and solidifies.
Benefits:
Saves costs
- The thread does not cut
Non-cutting thread-forming
Low clamping force and great thread flank coverage
- The TRILOBULAR shape of the screw core is combined with the thread’s flank radius profile
High clamping force
- Thanks to low clamping forces
High load-bearing capacity
- Thanks to the large thread flank coverage area
- Reinforcing thread that forms in the connected material
Loss prevention (less chance of screw loosening)
- Negligible clearance and self-locking tight thread
The formed thread corresponds to the standard metric thread
- If necessary, the GEFU thread-forming screw can be replaced with a screw with a metric thread.
The applicable application or component must be tested beforehand for compatibility with the thread-forming GEFU screw. Please see standard DIN 7500-2 for reference values for correct initial hole diameter choice.
