Self-tapping screws form a nut thread in cast blind holes, rim holes and drilled, lasered and punched sheet metal parts. Unlike thread cutting, self-tapping does not interrupt the material structure in the receiving thread. Instead, the material is displaced and strain-hardened.
Benefits:
Cost savings
- Eliminates thread cutting
Non-cutting thread formation
Low rolling torques with high thread flank overlap
- TRILOBULAR shape of the core diameter combined with the radius profile of the thread flanks
High clamping force
- Due to low rolling torques
High load-bearing capacity
- Due to large thread flank overlap
- Due to strain-hardened counter thread (nut thread)
Protection against loss (reduced likelihood of screw working loose)
- Play-free and self-locking thread seating
The formed thread corresponds to a standard metric thread
- Where necessary, the GEFU can be replaced with a metric screw.
The suitability of the GEFU for the application or component in question must be determined through preliminary testing. Guideline values for suitable hole diameters are specified in DIN 7500-2.
Examples of materials suitable for this type of non-cutting direct screw connection are ductile materials such as: steel (up to approx. 500 N/mm²), die-cast zinc, aluminium, copper and copper alloys etc.
