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 greater 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 screw can be replaced with a metric screw.
The suitability of the GEFU
® for the application or component in question must be determined by testing in advance. Guideline values for suitable hole diameters are specified in DIN 7500-2.
Examples of materials suitable for this type of non-cutting direct screwing are ductile materials such as steel (up to approx. 500 N/mm²), die-cast zinc, aluminium, copper, copper alloys etc.
