DIN 7500-1 (dimensions according to ISO 7046) with case-hardened (-O-) zinc-plated steel, blue passivated (A2K) with anti-friction coating

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.
Notice

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.
